The best UPVC multipoint replacement
I've recently been fitting the Yale Doormaster multi point locking
systems. I'm impressed with the quality and how quickly these rescue locks can be
installed. The operation is smooth and sturdy and the keeps / strike plates are fully adjustable so they will work first time. A complete system
replacement on average will take about 25 minutes with the Yale Doormaster. The
separate keeps and strike plate make a
world of the Yale Doormaster make all the difference.
