Cylinder day and night lock PC55 with stainless steel front plate

Cylinder day and night lock PC55 for interior doors

Want to lock your interior door with a profile cylinder? Then choose the cylinder day and night lock in the popular PC55 size. This mortise lock features a stainless steel faceplate, which not only provides a modern look but also ensures a long lifespan. It's the standard choice for doors requiring additional privacy or security through a cylinder.

Tip: always combine stainless steel mortise locks with matching stainless steel door fittings for a unified look in your interior.

Adjust the latch of your mortise lock in three steps

It doesn't matter whether your door swings left or right. The latch of this deadbolt is reversible:

1. Insert a flat-head screwdriver into the slot-shaped opening in the lock case and push the plate up.

2. The latch slides out of the forend.

3. Turn the latch to the correct position and press it firmly back into the lock. Now you can install the lock directly into your door.

Choosing door fittings for your PC55 door lock

Avoid surprises and always measure the backset of your current lock first; this Lavuzo version has the standard 50 mm backset. Because this is a PC55 lock, you'll need door hardware with the exact same backset (55 mm). This ensures a seamless fit between your handle and cylinder escutcheon or backplate on the new lock.
