Cylinder mortise locks
A mortise cylinder lock is designed to be operated with a suitable profile cylinder. The lock mechanism is installed inside the door; the hardware finishes the exterior. Compare the center distance, backset, and faceplate with the existing setup. Also check which cylinder and hardware you need to complete the door assembly.
A cylinder mortise lock for a euro-profile cylinder
A cylinder mortise lock is the lock case operated with a suitable euro-profile cylinder. The mechanism is inside the door; the cylinder and the visible hardware together form the operating mechanism. This makes it a different solution from a lever lock with a traditional bit key.
In this collection, you can compare versions with different forend colors. First choose a lock that fits in terms of function and dimensions. Then match the cylinder and the finish on both sides of the door accordingly.
55 mm PC, backset and cylinder to be checked separately
The current product data specifies a center-to-center distance of 55 mm for these cylinder mortise locks. This is not the cylinder length. The required cylinder size depends, among other things, on the door and hardware. Therefore, compare the lock's dimensional drawing and the connection specifications of the complete combination.
| Stated | What does it say? | Do not confuse with |
|---|---|---|
| 55 mm center-to-center distance | Distance between the handle spindle and cylinder axis | Cylinder length |
| Backset | Position of the spindle from the forend | Door thickness |
| Forend | Visible finish on the door edge | Size of a door backplate |
| Cylinder size | Length that must fit the door and hardware | External dimensions of the lock case |
Suitable hardware around the cylinder
With a door handle on a rose, finish the cylinder opening with a suitable cylinder rose. A backplate with a cylinder hole is a different solution. In that case, the backplate's fixed center-to-center distance must also match that of the lock.
A cylinder opening does not automatically make a lock suitable for every exterior door. For a front door, assess the complete combination and the stated application. Also review the front door hardware and use only verifiable product specifications as your basis.
Installation, use and maintenance
- Compare the lock case, faceplate, distance between spindle and cylinder, and backset with the existing door.
- Check the cylinder fit and scope of delivery separately.
- Test the mechanism with the door open and check the alignment of the strike plate.
- Use the key without force and follow the maintenance advice for the lock and cylinder.

Frequently asked questions
Is a profile cylinder included?
This must be clear from the product's scope of delivery. A cylinder mortise lock and the profile cylinder are separate components. Therefore, do not automatically assume a complete combination.
Does PC 55 mean that the cylinder must be 55 mm long?
No. The stated 55 mm is the distance between the handle spindle and cylinder axis. The required cylinder length is determined separately based on the door and hardware.
Can I replace a warded lock with a cylinder mortise lock?
That is only possible if the dimensions and the door are suitable for the new combination. The opening for the cylinder and the hardware differ from those of a warded-key version. Compare everything before dismantling.
Is a cylinder mortise lock always suitable for a front door?
No. The application and specifications of the specific lock must support this. Check the complete door assembly; the mere presence of an opening for a profile cylinder is not proof of suitability.
