FAQ

Product Details

Is this mortice cylinder hook bolt suitable for residential sliding doors?

Yes. This lock is designed for residential use and is intended for sliding doors made from wood. It uses a mortice case and a cylinder operated mechanism to provide secure locking for domestic applications.

What sizes do I need to check before installing the Mortice Cyl Sliding Dr Lock 55/85mm?

You should confirm the backset of 55 mm and the case size of 85 mm to ensure the lock matches your door preparation. The forend width is 20 mm, which is important for alignment with the existing rebate or template.

Will it work with a profile cylinder, and is it prepared for one?

It is prepared for a profile cylinder, meaning you can use a compatible cylinder to operate the lock. If you are matching an existing system, it is worth checking the cylinder type already fitted to your door.

What is the appearance and finish, and where will it suit best?

The forend and striking plate are supplied in satin stainless steel, giving a modern, low glare look. This finish typically suits contemporary and classic interiors where you want a consistent stainless effect across other ironmongery.

What comes in the box, and do I need a separate strike or face plate?

The lock is supplied with 1 mortice lock and 1 striking plate. This means you have the key components needed for basic installation of the locking function, but you should still check whether your door already has the correct fixing points.

How wide is the forend and what does that mean for the door cut out?

The forend width is 20 mm. This affects how the face plate sits in the door and how the mortice aligns with the rebate or existing cut out, so it is best to measure your prepared area or use the relevant template during installation.
