Guide to cylinder rings
At VillaHus we have a large selection of cylinder rings in brass, copper, chrome and nickel, tin and steel. In the cylinder ring there is either a drop-shaped hole or an oval hole for the lock which is placed in the door. Each hole fits each lock, which means that the cylinder ring with the drop-shaped hole fits a PZ lock, while a cylinder ring with an oval hole fits an ASSA lock.
We will be more than happy to guide you through the process if you need guidance.
