The Union 3G220 is a High Security Deadlock designed for use on timber doors with narrow stiles such as fully glazed doors. Unlike many other narrow stile locks, this lock has excellent protection against all common forms of attack including a positive 20mm 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 32mm dia, one covered and one plain in matching finish. Alternative keyhole escutcheons can be found in any of our door furniture collections if required.
Due to size limitations this lock is not certified to BS3621. However, it is considered by most insurance companies to be equivalent to the current standard.
Rebate conversion sets are not available for this lock and it should only be used on doors with plain meeting stiles.
Detailed advice on the selection of mortice locks and latches can be found in our [Mortice Locks & Latches Specification Guide].
For best results and long life, this lock should be lubricated with a light machine oil at least once a year.
This lock is supplied "to differ" whereby each lock is operated by it's own individual keys. Please contact us for details and prices for this lock to be supplied in groups operated by the same key ("to pass" or "keyed alike").
