CROWN SLIDING/FOLDING RANGE
We are pleased to announce our new aluminium sliding/folding "bi-fold" door into the Crown range. This stunning new addition to the Crown aluminium door family will be exceptionally popular with its unique Shootbolt & 'D' Handle and continuous hinges.
The innovative hinge means that there are no bulky or unsightly hinges to disrupt the contemporary sightlines.
The door features hardware designed specifically for doors - as opposed to 'window' hardware utilised on some
doors of this type. This allows the Crown Sliding/Folding Door to not only be securely
locked but also used as a main entry or exit operable from both inside and outside, using our robust & secure Multi-Point Lock.
