Profile cylinders & double cylinders for doors
Profile cylinders and double cylinders are central components of door locking systems. They are selected to match the existing mortise lock and door thickness and are available in various lengths and designs. At Fenstergigant, you will find profile double cylinders for front doors, entrance doors, and other suitable doors from various manufacturers.
Profile cylinders are inserted into the designated door lock and operated using a matching key. When replacing one, it is particularly important that the length and design of the new locking cylinder match the existing door. Before ordering, you should therefore measure the existing cylinder and determine the required internal and external dimensions.
A double cylinder can be operated from both sides of the door with a key. The required cylinder length depends on the door leaf, the hardware, and the installation situation.
