The Bell "Universal" fits to conventional pull screw sizes Ø 3,9 - 5,5 mm but can also be used with larger screws such as the "Pittbull" pull screw. The pulling mechanism of the bell has been especially modified to fit the "Pittbull" pull screw.
The Bell "Universal" comes into its own when used for locks with wide keyways, such as dimple pin tumbler locks.
The Bell is made from hardened steel for year-long use. The pulling mechanism has a very fine, hardened M12 thread for smooth working without having to exert any greater strength. In the case you need to replace parts, contact us! We have a constant stock of spare parts.
