Mortice Locks are more than a locking mechanism; they pledge to enhanced security, seamlessly integrated within your door. Unlike their surface-mounted counterparts,  mortice locks blend strength with aesthetics, offering a cleaner look and fortified security. These locks are categorised into deadlocks and sash locks, each serving distinct purposes.

In the upcoming section, we're delving deep into the world of door locks, focusing on three pivotal types: Sash Locks, Dead Locks, and Bathroom Lock. Each lock serves a unique purpose, ensuring security and privacy across various settings in your home or office. Sash Locks merge the functionality of a deadbolt and a latch within a single mechanism, offering a dual-function solution that's both secure and convenient. Ideal for doors with handles, these locks ensure your door stays closed even when not locked, thanks to the latch mechanism. On the other hand, Dead Locks simplify security by focusing solely on the deadbolt component, providing a robust barrier against intrusion with options for keyless egress. Lastly, Bathroom Locks specialize in maintaining privacy with a straightforward locking mechanism, excluding traditional keys in favour of a spindle system for easy access and emergency safety features. Join us as we explore these essential security features, equipping you with the knowledge to choose the right lock for every door.

A Sash Lock, often referred to as a mortice sash lock, skilfully combines a deadbolt and a latch within a single case, marking it as a versatile choice for securing doors. This type of lock is particularly useful when paired with door handles, providing a dual-function mechanism. As you turn the key, the deadbolt is activated, securing the door, while the lever or knob retracts the latch, allowing for easy access when unlocked. The beauty of a sash lock lies in its simplicity; even when the door is not locked, the latch ensures it remains closed by striking against the keeper. Engineered for both security and convenience, sash locks can operate through a key with a lever mechanism or a cylinder, and may even include thumb turns for those preferring keyless egress. Commonly found alongside lever handle sets, sash locks offer an effective solution to securing your home or office with an added layer of convenience.

Deadlocks may bear a resemblance to sash locks in appearance, but they are notably smaller and solely accommodate the deadbolt component, making them a popular choice for bolstering security. Essentially, a deadlock is a locking mechanism that consists exclusively of a deadbolt. This type of lock is highly valued for its simplicity and robustness in securing entrances. It can be operated through either a lever mechanism or a cylinder, offering versatility in its use. Additionally,  deadlocks can incorporate thumb turns, facilitating keyless egress applications. This feature is particularly beneficial in emergency situations where a quick exit is necessary, providing both safety and convenience. By integrating deadlocks into your security setup, you're not just adding an extra layer of protection; you're investing in peace of mind.

Bathroom locks play a pivotal role in maintaining privacy within homes, catering specifically to bathrooms, en-suites, and downstairs WCs. Unlike their more secure counterparts, these locks aren't designed with levers or high-security features. Instead, their purpose is straightforward: to prevent the door from being opened to ensure privacy when needed. A noticeable feature of a bathroom lock is the absence of a keyhole. Instead, you'll find an 8mm spindle hole (or follower) for the handles to operate, alongside a 5mm spindle hole for the bathroom turn. If your setup includes a bathroom lock, you'll need a set of bathroom lock handles on a backplate (note: not privacy handles) or, for handles on a rose, a bathroom turn—be sure it has a 5mm spindle, as 8mm versions exist but are less common. To engage the lock, a simple 45-degree turn of the bathroom turn is sufficient to throw a bolt across and secure the door; reversing the turn unlocks it. Importantly, most bathroom lock handles or turns feature a coin slot on the outside, a thoughtful safety measure for instances where a child might lock themselves in or if an adult experiences a fall, allowing for emergency access. This design intricacy ensures both privacy and safety, making bathroom locks an essential component of home security.

When it comes to enhancing the security of your home or property, understanding the different types of Sash Locks and Dead Locks available can make a significant difference. These locks come with varying amounts of levers, where the rule of thumb is: the more levers, the higher the security. Specifically, 2 and 3 Lever locks provide basic protection and are typically suited for internal doors. These locks are often found in older properties, offering the advantage of fitting into doors as thin as 35mm, unlike the slightly thicker 5 Lever locks . For external doors, insurance companies usually require locks with a higher security level, such as 5 Lever locks that are kite marked with the BS 3621 rating. While you can find budget options that lack this certification, we highly recommend the ERA Fortress 5 Lever Sash Lock range for optimal security and peace of mind.

Moreover, T.H. Wiggans Ironmongery offers the unique service of creating locks that operate with the same key, known as "Keyed Alike." This option is particularly convenient for those who prefer using a single key for multiple doors, such as the front and back doors, or for stable doors that require a lock on each but wish to avoid the hassle of carrying multiple keys.

Additionally, Mortice Sash Locks and Dead Locks are designed to be compatible with Euro and Oval Profile cylinders, with Oval cylinders nearing discontinuation but still available for replacements. Euro profile cylinders are commonly seen on Composite or UPVC doors and can also be adapted for use on wooden doors with the appropriate lock. It's important to note that while the basic principle is that more pins equal higher security, these cylinders also come with features like anti-bump and anti-pick for enhanced protection. Both insurance-rated and non-insurance-rated versions are available, catering to a wide range of security needs. For more detailed information on cylinder options and to discover the best solution for your security requirements, don't hesitate to contact us at T.H Wiggans Ironmongery.

Horizontal mortice locks serve a unique and valuable purpose in both traditional and contemporary homes. Primarily utilized with  Mortice Knobs, these locks are a go-to solution for avoiding the discomfort of knocking your knuckles against door casings. The design of a horizontal mortice lock clearly positions the knob 4-5 inches away from the casing, thus offering ample space for a comfortable grip and easy operation.

These locks are typically available in 3 Lever versions. Their niche appeal means that you might not easily find an insurance-rated horizontal mortice lock . The cost and demand for such certification often deter manufacturers from pursuing it. However, for those concerned with insurance compliance while desiring the aesthetic and functional benefits of a horizontal lock, supplementing with an insurance-rated Dead Lock either above or below the primary lock can provide a viable solution. This approach has been adopted for enhancing security on large doors, creating a fortified, multiple-lock deadlock scenario.

This tailored solution ensures that homeowners can enjoy the ergonomic benefits of horizontal mortice locks without compromising on security requirements, blending tradition with peace of mind.

When selecting the right mortice lock for your door, understanding the available sizes and key dimensions is crucial. This section breaks down everything you need to know about mortice lock sizes and the importance of each dimension for a perfect fit.

Mortice locks come in a variety of sizes to accommodate different door thicknesses and security needs. The most common sizes you'll encounter are 2.5” and 3”, which cater to a wide range of standard doors. However, at T.H. Wiggans Ironmongery, we understand the diversity of our customers' requirements. That's why we offer an extended range of sizes, including 2”, 4”, 5”, and 6” versions, ensuring that no matter the door, we have a lock that fits.

Key Dimensions Explained

To ensure a seamless fit and optimal security, it's important to familiarize yourself with the five key dimensions of a mortice lock. These dimensions are critical for selecting the right lock for your door, whether you're installing a new one or replacing an old lock.

Backset

The backset is a fundamental measurement, defined as the distance from the centre of the keyhole to the edge of the lock. Typically, backsets measure either 44mm for a 64mm (2½”) lock or 56mm for a 76mm (3”) lock. The choice of backset often depends on the door's design, such as the presence of a glass panel, which usually necessitates a 2½” backset. Always measure your door to confirm the appropriate backset size.

Centre

The centre measurement is taken from the keyhole or cylinder's centre to the follower hole's centre (the square hole that accommodates the handle spindle). It's worth noting that this measurement is not necessary for deadlocks, as they do not feature a handle.

Case Depth

Case depth refers to the lock's depth when installed into the door, measured from one edge to the other. In the UK, the standard case depths are typically 64mm (2½”) and 76mm (3”). It's essential to verify the case depth before installation, especially if you're working with an existing door setup.

Case Height

Case height is the measurement from the top to the bottom of the lock case. This dimension ensures that the lock fits perfectly within the door's designated space, avoiding any protrusion or misalignment.

Forend (Faceplate) Dimensions

• Forend (Faceplate) Length: This is the visible length of the lock once installed, which can have either a squared or rounded end, contributing to the lock's aesthetic and functional fit within the door.
• Forend (Faceplate) Width: Similarly, the width of the forend or faceplate is crucial for a flush fit, ensuring the lock's visual appeal and structural integrity.

Understanding these dimensions is key to selecting the right mortice lock for your door. Whether you're aiming for aesthetic harmony or enhancing your home's security, knowing these sizes and measurements will guide you in making an informed decision.

Installing a mortice lock might seem like a daunting task at first glance. However, armed with the right tools and a sprinkle of patience, it can transform into a rewarding DIY project that enhances your home's security. Below, you'll find a streamlined guide to the installation process, tailored to ensure clarity and ease. Do keep in mind that each lock might come with its own unique set of instructions, so it's always a good idea to give those a read before you dive in.

Measure Your Door

First things first, you'll want to measure your door meticulously to ensure the new lock fits like a glove. Key measurements include the backset (the distance from the edge of the door to the center of the keyhole), the case depth, and the dimensions of the forend (or faceplate). Getting these numbers right from the get-go can save you a heap of trouble down the line.

Remove the Old Lock (If Applicable)

If there's an old lock already in place, you'll need to remove it carefully. Unscrew and gently take out the existing lock, making room for the new champion of your door's security.

Mark and Drill

Next up, outline the new lock's future home on your door. This involves drilling a series of overlapping holes to create a cozy space for the lock case. Precision is key here to ensure everything lines up properly.

Chisel Out a Perfect Fit

With the drilling done, it's time to chisel out any excess wood to ensure both the lock case and faceplate fit snugly. This step is crucial for a clean, professional-looking install.

Fit the Lock

Now, secure the lock in place, ensuring it's perfectly flush with the door edge. This is when your door starts to feel the newfound security.

Align the Keyhole and Spindle

Mark and drill for the keyhole and spindle, ensuring they align flawlessly with the lock mechanism. This alignment is vital for the smooth operation of the lock.

Apply the Final Touches

Fit the faceplate and strike plate, then give the lock a test run. Make any necessary adjustments to ensure the operation is as smooth as silk.

Care and Maintenance: Keeping Your Mortice Lock in Tip-Top Shape

Even the most robust lock requires a touch of tender loving care to keep it turning smoothly over the years. A bi-annual application of non-acidic mineral oil, accompanied by a gentle wipe-down with a damp cloth, will ensure your mortice lock continues to function beautifully for years to come.

By following these steps, not only do you enhance your home's security, but you also gain the satisfaction of having completed a valuable home improvement project yourself.

When delving into the world of mortice locks, understanding the terminology can make a huge difference. Here's a glossary to help you get to grips with the key terms:

Forend (Faceplate)

The forend, also known as the faceplate, is a crucial component of the lock case. It's the part through which the lock is attached to the door and allows the latch or deadbolt to pass. Depending on the design, faceplates can have either a square or round end, contributing to the lock's aesthetics and functionality.

Spindle

The spindle is a square section drive bar, typically 8mm in width, that penetrates the drive of the lock. It connects to the handle set levers or knobs, facilitating their operation. Turning the lever causes the spindle to rotate, which, in turn, activates the lock's drive (follower). The appropriate spindle length varies based on the door's thickness and the depth of the handle lever's receiving element.

Centres

Centres refer to the vertical distance between the lock spindle and the centre of the keyway in the gearbox. This measurement can differ among lock systems, though 57mm is a common standard. Understanding the lock's centre dimension is vital for choosing the correct handle, ensuring a perfect fit and seamless operation.

Rebate

A rebate is a rectangular recess cut along the edge of a door frame to accommodate the door leaf. This feature is also employed in the meeting rails of double doors, creating a flush closure between the door leaves. For doors with rebated edges, specially designed rebate conversion kits are necessary to properly fit door locks and keeps.

Backsets

The backset measures the distance from the lock's keyhole to its outer edge. This dimension is key to selecting the right lock, as it influences how the lock will fit and align with the door and frame.

Keeps/Striker

The keep, or striker, is an element mounted on the door frame's fixed portion. It interacts with the lock's moving part (such as the bolt) when the door is locked. Ensuring the keep or striker is correctly aligned and installed is essential for the lock's effectiveness and security.

Understanding these terms not only aids in selecting the right mortice lock for your needs but also enhances communication with professionals and retailers, ensuring you get exactly what you're looking for.
