Yale P-ET3030-SNP Euro Thumbturn Cylinder, 3 Keys Supplied, Standard Security, Visi Packed, Suitable for All Door Types, 30:10:30 (70 mm), Nickel Finish

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.
