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 a boxed strike plate / keep, the 20mm hardened anti-saw bolt 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 different finishes, these are suitable for a huge range of design schemes, matching up with 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.
As standard these are designed to work with sprung door handles, but if you want to use unsprung door handles, please consider the heavy duty spring upgrade which will stand up to the test of the additional force required to return the handles to the horizontal position - in the long run, this is a cheap upgrade that will serve you well! Again this is a custom job so please allow a day or so extra to fulfil these orders.
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
Important: These items are built-to-order specially for you and are not 'off-the-shelf' items. Therefore please allow a 2-3 week manufacturing period before dispatch. As such, these products they are deemed non-returnable so please double-check your requirements before placing your order.
Our product specifications are given in good faith but can be subject to manufacturer change without notice. Should an attribute be of essense to your purchase, please feel free to contact us first for confirmation.
