LocksOnline Imperial Euro Profile Sashlock Case

One of the distinct advantages of a euro profile lock case over a traditional lock case is the ability to swap out cylinders without having to change the whole lock.   This allows you to take advantage of the diverse configuration of master-keying and keying alike available on euro cylinders, and also means should you need to change the locks, you only have to swap out the cylinder.  

This is a perfect example of a retrofit euro profile lock which offers the same measurements as many common sashlocks whilst allowing you to upgrade to a euro cylinder locking solution.  What's more, the Imperial range offers three PZ centre sizes - 48mm (standard for Euro profile locks), 51mm (unusual but absolutely critical for a retrofit of this size), and 57mm which is especially considerate towards those looking to upgrade from 5-lever locks to Euro profile.

Available in 63mm (approx 2.5"), 76mm (approx 3") and 101mm (approx 4") case sizes offering 45mm, 57mm and 82mm backsets accordingly, this set of measurements is common amongst sashlocks so should retrofit the majority of existing installations quite well with minimal modification required.   Of course, if upgrading from a standard lever based mechanism you'd need to modify the keyhole to accommodate a euro cylinder. 

In the interest of security and a more quality installation, these locks are designed to accept bolt-through fixings also.  This is vital for things like security escutcheons and many high quality handles which will require you to fit them in such a way that they clamp together through the door, rather than relying on wood screws binding into the door itself.   To suit the vast majority of bolt-through fixings for handles, the case is pierced around the square follower to accept these fixings at 38mm apart, measured from centre-to-centre.   On the two larger models, this is offered both horizontally and diagonally, but on the smallest model is only available diagonally due to physical constraints of the components inside the lock case. 

Around the keyhole then, you have bolt-through fixings set at a 20mm distance (again measured centre-to-centre) for bolt-through escutcheons where the screws are closely fitted around the lower section of the euro cylinder.   Please note, the images show the old version which had both 38 and 20mm holes at the euro aperture, but now is only the 20mm due to a design revision.  

Rebate kits are available if you have a rebated set of double-doors.
