Please can anyone offer a method of removing a handle assembly from a aluminium d/glased door. The handle is mounted (each side of the door) on a aluminium extrusion and appears to be held in place with a plastic moulding pushed inside it at the top and bottom and also by the lock barrel (that is easily removed), I am not certain if the extrusion should be jumped off of the plastic end plugs or if the plastic end plugs should be slid out of the extrusion. The reason for removing the handle and lock is in a attempt to repair the outer handle so the dead locks can be operated on leaving. Many thanks for any help you can offer. Also where can this type of locking arrangement be purchased. Many thanks Derek
