These espagnolette, or 3 point locking door locks are an extremely secure locking system. They work in conjunction with our Euro Cylinder Locks. These espagnolette locks are made to a very high standard, keeping your doors very secure. These locks are to be used with Unsprung handles due to the upward movement of the handle to engage the 3 point locking system. We do, however, stock a few specially made handles that have a small spring incorporated so that the handle can still lift upward but will then spring back to its original position. An example of this handle would be the D4313, Avon Lever Door Handle.
