40:10:45 (95mm) Euro Double Cylinder

The cylinder is suitable as a replacement product on PVCu, timber and composite doors that require a standard level of security.For this, we recommend using a PTFE based lubricant. A small amount of lubricant should be applied to the key and then inserted into the cylinder. Rotate the key a couple of times in line with the normal locking function. Remove the key from the cylinder and wipe away any remaining lubricant to ensure it isn’t transferred onto other objects.
