The 3G135 is part of UNION's C-Series.  This series of locks replaces the old Chubb locks, in this case this is a replacement for the Chubb 3G135 Detainer Lock.

The Detainer type of lock offers a lot more key combinations than a typical lever lock, and is therefore considered superior to its equivalent lever type locks.  Further to this, these locks are also Anti-Pick, Anti-Saw and are resistant to brute force attacks.

These locks still use the unique key profile of the old Chubb locks, which is special to these locks and had previously been a profile only available directly from Chubb.  However, we can now cut you additional genuine keys for these locks should you require more - simply select how many extra keys you would like when placing your order. 

This detainer lock is also suitable for use on fire doors - both 30 and 60 minute fire doors in fact!  So if you're looking for a very strong lock for your fire doors, then the 3G135 would certainly fit the bill!

To top it all off, these come with a delightful 15 year guarantee!
