Screw change pin / scissor change pin for doors that are only drilled on one side and where no handle is to be mounted on the other side. It replaces the standard handle pin and is inserted into the lock cylinder. By tightening the included nut, the pin expands and cannot be pulled out of the lock cylinder. An additional locking screw adjusts the length to the handle. Example: You have a front door that only has a pull rod, handle plate, or push bar mounted on the outside and you want to use a handle on the inside. For this, you need a secure connection between the handle and the handle pin. To establish a secure connection, simply use the screw change pin as described above, and the handle can be securely mounted. Additional technical features: Surface: galvanized.
