LocksOnline Imperial BS3621 5-Lever Deadlock

These British Standard BS3621 mortice dead-locks have been designed and built right here in Britain by Imperial Locks based in Willenhall, England.  Built for security and lasting performance, these locks come with a fantastic 10 year mechanical guarantee! 

BS3621 locks are considered these days to be the industry standard for satisfying typical insurance requirements.  You will often see them labelled as 'Insurance Approved' - and while in most cases this is true, it does all depend on each individual insurance policy, so if you're unsure, while these are normally a safe-bet, check your policy or go ahead and speak with your insurer and they'll be able to tell you if you're unable to make sense of your policy!

Supplied with matching keyhole escutcheons with the external cover-plate, as well as a metal boxed keep for the frame, the 20mm hardened anti-saw deadbolt on these ensures a good strong hold into the frame, and the British Standard kitemark stamped into the faceplate gives you the assurance that your door is secured with a genuine British Standard BS3621 locking solution. 

Available in six stunning finishes, these work well with a huge range of interior design schemes, allowing for seamless integration with your door furniture - from standard satin brass / stainless steel finishes (a brushed / matted finish) and also the more traditional polished brass and polished stainless finishes.  In addition to this, we have the truly stunning bronze and black finishes, which you'd be hard-pushed to find with any other British Standard door locks. 

We are also proud to offer free keying alike on these locks!  A service that we've not seen anywhere else on these. This allows you to have the same keys on multiple locks!  

Please be aware that the Imperial Locks range is manufactured to order for you specially - so please allow additional time for these to be dispatched!

These locks are fire-tested to BS EN 1634-1:2000
