LocksOnline Imperial 5 Lever Sashlock

This five lever sashlock is one of the most popular of the Imperial Locks range, offering 5 lever security on the standard 2.5 inch, 3inch and 4inch lock case sizes (that's 63mm, 76mm, and 101mm). 

5-Lever locks are now considered to be the base-level of security required for external facing doors; that is, if it's fitted on a door that sits on an outside wall and therefore protects the building from intruders, then nothing less secure than 5-lever should be considered for that application.   This 5 lever configuration offers hundreds of possible differs per lock due to the number of variations available on each lever within this range of locks.  To ensure complexity in the configuration, the less complex arrays of levers available are discarded and not used, ensuring that the levers in every lock are sufficiently diverse. 

These lock cases are designed to compliment bolt-through furniture, which when it comes to door handles, is quite important as it allows for a secure, firm fit onto the door and means the handles are not relying on wood screws simply being screwed into the wood.  We always try to recommend bolt-through handles and the design of this lock considers this.  The case hosts a set of bolt-through fixing holes at 38mm centres - the most common distance between most bolt-through fixings.   It is worth noting that on the 63mm model, these holes are diagonal only due to space limitations in the lock body itself, while the 76mm and 101mm case sizes offer both a horizontal and diagonal pair of holes. You'll see this in the photos. 

For added security against attacking, these locks are built with two hardened steel rollers within the deadbolt.  This helps protect against sawing, as a saw blade relies on a static surface to cut through, whereas once they were to hit one of these hardened steel rollers, the idea is that by them freely rotating with the saw, it would be incredibly difficult to try and get any further - and even if they were eventually able to cut through, they'd soon be tasked with the second roller.  So these rollers are really worth considering if comparing with other locks. 

As a free service to our customers, we also offer keying alike at no extra charge across the whole LocksOnline Imperial range.  So if you'd like your locks to all work off the same key, choose keyed alike before adding to cart.  These can be keyed alike to other locks within the LocksOnline Imperial range that you may want to order, again at no extra charge.  Just choose keyed alike on each of them, and if you want some keyed alike together and others keyed alike together, but not ALL together, just pop it in the order notes during checkout! 

Extra keys are also available - we can do this in our workshops here as well as the keying alike.

We are also able to offer a manual upgrade of the spring inside these locks, if you want to use unsprung door handles or door knobs with these, then you would need to go for the upgraded spring as the standard springs in these and other locks are designed to work with self-sprung handles. 

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
