2 Lever Mortise Lock

 set is designed to be mortised directly into the door edge. It provides a clean, professional finish that surface-mounted locks simply cannot match.

This lock combines essential functionality with straightforward operation. The latch bolt, operated by a lever handle or knob, allows for easy opening and closing. The deadbolt, operated by a key from either side, provides a secure locking function when privacy is desired.

Understanding the 2 Lever Mortise Lock

A mortise lock is designed to be installed into a pocket cut into the edge of the door. Unlike cylindrical locks that fit through a single large hole, mortise locks are recessed into the door, making them more secure and stable. They consist of a rectangular metal box called the lock case that houses the locking mechanism.

The 2 lever refers to the internal mechanism that provides the lock’s security. The levers are spring-loaded plates inside the lock. They must be lifted to a specific height by the key’s unique cuts to allow the bolt to move.

It is important to note that 2 lever locks are not suitable for external doors due to their lower security rating. They are, however, perfectly adequate for internal use where the primary need is privacy and basic security, rather than high-security protection against determined intruders.

Key Features of a 2 Lever Mortise Lock

This is a sash lock as opposed to a deadlock. It combines two functions in one unit. The spring latch bolt is operated by the lever handle, allowing easy opening and closing. The deadbolt is a sturdy bolt that is locked or unlocked by the key from either side of the door, providing the actual security when locked.

This two-way action makes the lock suitable for use with lightweight sprung lever handles or knobs.

This 2 lever mortise lock comes as a complete set, providing everything you need for a successful installation.

The lock case is a robust metal casing, typically 64mm or 76mm, designed to be recessed into a mortise cut into the door edge. The reversible latch bolt can be easily reversed during installation to suit doors hinged on either the left or right side. This means one lock model works for all door configurations.

The deadbolt is a solid bolt that provides the locking function. The strike plate is a matching metal plate fitted to the door frame, receiving the latch and deadbolt to secure the door. The lever handles are a pair of lever handles for operating the latch. Fixings include all necessary screws for attaching the handles and strike plate.

Each lock is supplied with two durable nickel plated keys. Key differs refers to the number of unique key combinations available for a particular lock model. A standard 2 lever lock typically offers around 20 key differs. This is adequate for internal residential use, ensuring it is unlikely that another lock of the same type in a different home will be operated by the same key.

Understanding Lock Measurements

To ensure you purchase the correct lock for your door, you need to understand two key measurements.

Case size is the physical size of the metal lock case. Common sizes for internal doors are 64mm suitable for thinner doors typically up to 35 to 40mm thick. 76mm is suitable for standard internal doors typically up to 44 to 54mm thick.

Backset is the distance from the edge of the door to the center of the keyhole or the center of the handle spindle. Standard backsets are often 44mm or 57mm. You must measure your door’s existing hole positions to ensure the new lock will fit correctly.

Materials and Construction

Quality 2 lever mortise locks are constructed from durable materials to ensure long-lasting performance in an internal environment.

The lock case is typically made from robust steel with a corrosion-resistant finish such as electro-brass, powder-coated, or zinc-plated. The bolt and latch are often manufactured from solid brass for smooth, reliable operation.

The forend is the visible faceplate on the door edge, usually finished in brass or chrome to match the handles. The keys are durable nickel-plated steel.

Installation Overview

You will need a pencil, tape measure, chisel, hammer, drill with appropriate bits, and screwdriver.

First, mark out the door. Mark the position of the lock case on the door edge and the center of the keyhole and handles on the door face.

Second, mortise the door edge. Cut a rectangular pocket in the door edge to the depth and height of the lock case. This requires a chisel and hammer or a router for a cleaner finish.

Third, drill for handles and keyhole. Drill the necessary holes through the door face for the lever spindle and keyhole.

Fourth, fit the lock case. Insert the lock case into the mortise and secure it with screws. Mark the position of the forend, chisel a shallow recess for it, and screw it in place.

Fifth, install the handles. Assemble the lever handles according to the manufacturer’s instructions, inserting the spindle through the lock case.

Sixth, fit the strike plate. Close the door, mark the position of the latch and deadbolt on the frame, and chisel a recess for the strike plate. Secure the strike plate with screws.

Seventh, test. Test the operation of the handle and the key before final tightening.

Frequently Asked Questions

What is the difference between a 2 lever and a 5 lever lock?

The number of levers refers to the internal mechanism’s complexity. 5 lever locks offer a higher level of security. They are the minimum standard required for external doors in many regions. They must also meet British Standard BS3621 for use on exterior doors. 2 lever locks are for internal use only, offering basic privacy rather than high security.

Is a 2 lever lock secure enough for a bathroom?

Yes, absolutely. For a bathroom or bedroom door, the purpose of the lock is privacy, not fortress-like security. A 2 lever lock provides an appropriate level of privacy. It prevents accidental opening while allowing someone to unlock the door from the outside with a key in an emergency.

Can I use this lock with unsprung lever handles?

This is a critical point. Most 2 lever mortise locks are designed for use with sprung lever handles. The lock case itself does not contain a spring to return the handle to a horizontal position. Therefore, it must be paired with handles that have their own internal spring mechanism. Always check the product description to confirm compatibility.

What does reversible latch mean?

It means the latch bolt can be turned around during installation to suit doors that open inward or outward, and for left-handed or right-handed doors. This makes the lock versatile and easy to fit without needing different models for different door configurations.

Can I use a 2 lever lock on a fire door?

Fire doors require specialized hardware that meets fire safety regulations. A standard 2 lever mortise lock may not be suitable. You must use hinges and locks that are specifically certified for use on fire doors. This ensures they perform correctly in the event of a fire.

What is a rebated lock?

If your door has a rebated edge, a lip that overlaps the frame, you will need a rebated 2 lever mortise lock. These have a cranked or bent forend to fit the rebate. Standard flat forend locks are for non-rebated square-edged doors.
