4 Point Door Locking System
Our doors feature our industry-leading four-point locking system. It features a hook, locking latch and two roller locks. We use a type of lock known as a RASP cylinder. The reason we use this is that it is a safer, more secure locking system as it prevents 'lock bumping' and 'cylinder snapping'. Our Premiumplus windows have multipoint locking as well, using the same type of system as we supply with our uPVC windows and doors.
