Piano locks
Ward locks are operated with a bit key and suit door hardware with a traditional keyhole. Match the color of the faceplate to the other door finishes. Before installation, check the center-to-center distance, backset, and cutout so that the lock and the selected backplate or key escutcheon fit together.
Mortice locks for operation with a bit key
A mortice lock is a lock fitted into the door, operated with a bit key. The key opening has a different shape from an opening for a profile cylinder. This distinction is important if you want to reuse existing hardware or assemble a complete new door.
This collection contains mortice locks with different faceplate colours. This allows you to match the visible finish on the door side to the lever handle and rose. However, start with function and size: a matching colour cannot make an incorrect connection fit.
Compare 56 mm centre distance and other measurements carefully
The current products specify a centre distance of 56 mm. This measurement describes the distance between the spindle and the key control. The backset and dimensions of the lock case are separate details. Check all of these for the selected product and do not assume missing measurements from another variant.
| Size or component | Meaning | Check when replacing |
|---|---|---|
| Centre distance | Distance between the lever handle and key control | Connection to the door backplate |
| Backset | Position of the controls from the forend | Existing hole in the door |
| Forend | Visible plate on the door side | Height, width and shape |
| Key opening | Opening for a bit key | Matching key escutcheon or backplate |
Combining a key escutcheon or backplate
With a lever handle on a rose, finish the key opening with a matching key escutcheon. With door hardware on a backplate, the opening and the fixed centre distance in the plate must match the lock. Also compare both options based on how well they cover old holes.
If you specifically want to use a profile cylinder, view cylinder mortise locks. This is a different method of operation and requires matching hardware. A lever lock and a cylinder mortise lock are not interchangeable names for the same product.
Installation, use, and maintenance
- Measure all connection dimensions and compare the dimension drawing with the old lock.
- Check the handing and follow the instructions for any reversible latch bolt.
- Test the key and handle with the door open before assessing the strike plate definitively.
- Keep the keyhole clean and use only maintenance products approved for the mechanism.

Frequently asked questions
What is the difference between a lever lock and a cylinder mortise lock?
A lever lock is operated with a bit key. A cylinder mortise lock works with a matching profile cylinder. The keyhole and the required hardware therefore differ.
What does SL 56 mean for a lever lock?
For these products, 56 mm refers to the specified center-to-center distance between the handle and key operation. Also check the backset, faceplate, and lock case; the center-to-center distance alone does not determine whether the lock will fit.
Do I need a keyhole rose?
With a door handle on a separate rose, a keyhole rose can finish the opening. A matching backplate with a keyhole offers another solution. Choose based on the existing hardware and the correct dimensions.
Are keys and the strike plate always included?
You cannot assume that. The contents may vary by product. Check the product page and identify any missing information before ordering a complete set.
