"Making an Entrance"
The telescopic door was primarily designed as an "in-line" package to fit entirely within the structural reveal depending on the wall thickness. The pre-assembled frame incorporating the support bar can be installed at the first fix stage allowing other trades to complete the walls and floors before the panels are fitted.
The two sliding leaves are connected by a sequencing device so that the primary leaf (fast door) reaches the fully opened or closed position at the same time as the secondary leaf (slow door) reaches its pre-set position.
