Please see installation instructions for exact calculation of door width and required door preparation details.
The vertical gap dimensions between the door leaves are 4 mm standard and are closed with the DS 9608 rebate seal. With model 50A, a gap dimension of 0.5 mm is alternatively possible without a seal.
The wall sealing profile must be slightly milled out in the centre or the vertical door edge must be rounded off towards the wall connection with an appropriate radius.
Other wall connection options can be found in the installation instructions.
In the open position, the folding package parks parallel or slightly inclined/V-shaped depending on the door thickness as well as the number of door leaves.
Model 50A (door hinge)
The door hinges are recessed into the upper and lower edges of the door (pivot hinge visible).
For the corner suspension variant with recessed door hinges, generally only solutions with 2 leaves of folding door systems are possible. The bottom guide track is mandatory here.
For the centre suspension variant, there is the option of using a bottom track or not.
In the variant without a floor guide, we recommend setting the gap dimension between the floor and the lower edge the door to 7–9 mm, since the pair of doors could otherwise come into contact with the floor because of the slightly swinging folding movement if the gap dimension is too small.
Model 50B (butt hinge)
The number of butt hinges depends on the door height.
With the corner suspension variant with butt hinge, systems must generally be planned with a bottom guide track. Exceptions are systems with max. 2 door leaves on both sides, which can also be designed without a bottom guide track.
For the centre suspension variant, there is the option of using a bottom track or not.
In the variant without a bottom guide track, we recommend setting the gap dimension between the floor and the lower edge the door to 6–8 mm, since the pair of doors could otherwise come into contact with the floor because of the slightly swinging folding movement if the gap dimension is too small.
Door alignment magnets are milled into the vertical door edge and are mandatory for door alignment.
