GU BKS 92PZ Narrow Sashlock Case - 35mm Backset

Finding a slim enough lock to fit narrow door stiles can be tricky - luckily this impressive lock from GU offers a perfect 35mm backset with 92mm PZ centres, and is also available with a U-Rail faceplate if required!  Or if this is not required you can simply choose the standard flat faceplate.

One distinct advantage with this GU lock against other narrow stile locks is its latch retraction functionality.  This allows you to withdraw the latch by turning the key, so if you wanted to not allow the use of a handle on the outside of the door for example, but still wanted to be able to gain entry via key, you could unlock the door by key and then proceed to pull the latch back by turning the key another quarter-turn.  This is immensely useful when considering things like access control where you may need to restrict handle operation on the outside but still need to be able to gain entry via key override.

Whilst on the subject of the latch; on these locks the latch is reversible so there is no handing to consider at all - it is a simple twist to reverse type latch reversal, which means you can quickly and easily change the handing of the lock as and when you are on-site about the fit the lock.

Because of the 92mm centres measurement on these lock cases, they are also fully DIN18251-2 compliant allowing for ample distance between the handle and locking solution (in this case, a cylinder is required for the locking part).
