The Union 2234E 80mm Keyed to Differ 5 Lever BS3621 Insurance Rated Sashlock Satin Chrome is one of the most widely-used locks for external doors. It is insurance company approved and has been tested to British Standard 3621:2004, making it one of the securest locks on the market today. For rebated double doors a rebate set is available to suit.

It has a quality steel case (red enamelled) and solid brass latch & deadbolt, finished with satin chrome finish.  

Other Variations

The lock is also available as a keyed alike lock, with an 67mm case size (44mm backset) and with a polished brass finish. Some of these variations can be found in the related products.

Security Feature Lock

The dead bolt has an extended throw of 20mm, as well as anti saw thrust pins to defeat any attempt to cut through the bolt. The case is reinforced around the levers to prevent drilling and in all it is completely burglar-proof. The case is pierced to accept bolt through handle fixings and the springing is strong enough to accept any of the un-sprung levers we sell.

Keyed Alike Combination

We can key alike a number of locks in any combination required  although we recommend no more than 6 locks are keyed to any one key variation.
