Probably one of the best locks of it's type ever made, the 3G110 is a High Security Deadlock that has been a popular choice for domestic and industrial/commercial entrance doors for nearly a century. Incorporating the famous Chubb 5 Detainer mechanism the lock has excellent protection against all common forms of attack including a positive throw solid brass deadbolt with hardened steel anti-saw rollers and hardened steel anti-drill plates. Originally bearing the Chubb name, it is now manufactured under the Union brand name. Produced in the same factory by the same people and using the same technology and parts, this lock remains "Chubb at Heart".
Manufacturer's standard keyhole escutheon sets are plain 32mm square in matching finish. Alternative keyhole escutcheons can be found in any of our door furniture collections if required.
Can be fitted to double doors with rebated meeting stiles when used with the rebate conversion set in the Related Items section below.
