Strong & Secure
We have developed a premium specification lock for the master door of the XP88 bi-folding door system. The strong & secure purpose made lock comprises six-point locking made up of latches and dead bolts. The door also includes quadruple locking catches on the intermediate panels, steel shoot-bolt locks that secure the top and bottom of the frames and pins that secure into one another when the door is closed.

Get the Steel Look
The slender frames of the XP88 bi-folding door make it the perfect system to replicating the popular steel look. We can achieve this by incorporating dark Georgian bars inside the glass, or the slightly more complex option of sticking aluminium bars onto both panes of the glass itself.
