Tosca Polished Chrome Curved Lever 48mm Euro Cylinder Door Handles

Euro profile handles have an enlarged keyhole shape cut out of the back plate. This Euro cut out in the back plate is used to house a key operated Euro Cylinder. The cylinder is used together with a Euro Sash Lock, which consists of a latch and a deadbolt and is mortised into the edge of the door. The lock also has the euro shape cut into it to allow the cylinder to pass through and come out on the opposite side of the door. These cylinders are available in various lengths to suit the thickness of the door/handles and various styles such as double key, key and turn, or single cylinder. The handles are fitted to either side of the door and are connected by a spindle. When the levers are pressed, the spindle rotates and operates the latch allowing the door to open. When the key or thumb turn is operated, the deadbolt on the lock is thrown and the door is then locked. The centre size refers to the distance between the centre of the spindle and the centre of the round part of the cylinder as dictated by the lock design. The handles are supplied complete with the spindle and fixing screws, but not with the lock or cylinder, which need to be purchased separately, and are normally specified to have a matching finish to the handles.
