£13.14 Inc VAT

This espagnolette window lock mechanism does not have any letters or numbers printed on it to aid identification.

To ensure that this is the part you require, we advise you to remove the espag window lock from your window and compare it to the photo provided here.

The gearboxes of the different types of espagnolette window lock mechanisms all look very different when you inspect the shape of them.

Once you are happy that the gearbox on your espagnolette window lock mechanism matches ours then you know you have found the correct type.

Please choose the correct Backset [A], Cam Height [B] and Rail Length [C], all explained in the introduction to espagnolette upvc window locks.

Bespoke Mushroom Height

Our standard mushroom height is 8mm. However we can fit 6mm or 10mm mushrooms for a small fee - see options on the left. Locks ordered with a mushroom height of 6 or 10mm are not returnable as they have been modified for you.
