UNION C-Series 3G220 Narrow Stile Detainer Deadlock

The UNION 3G220 directly replaces the old Chubb 3G220 narrow locks.  These have been rebranded and are now sold under the UNION brand owned by Assa Abloy.

The primary use for these locks is in narrow-stile doors such as aluminium framed doors, glass panelled doors and french doors etc, where the 'border' of the door (known as the door stile) is too narrow to accept a full sized lock.  Whereas these locks are only 54mm deep in total, with a 36mm backset.

With its force-resistance, anti-lock-picking and anti-saw security features, coupled with the extra-long 20mm bolt throw, these locks are a really good all-rounder for narrow doors which will offer a decent level of security.  The fact that they are detainer type locks rather than standard lever locks, means another layer of security is added by the fact that detainer locks offer a lot more key combinations than a normal lever lock!

These can also be used on fire doors - whether you're wanting to fit locks to 30 minute fire doors or 60 minute fire doors, these EN1634-1 tested locks are rated for use on up to 60 minute timber fire doors!

What's more, these are backed by a fantastic 25 year guarantee, giving you a great deal of peace of mind!
