Helaform sliding door systems are easy to choose and assemble

Before making your choice determine
- the weight of the door (kg)
- the dimensions of a door (m²) used outdoors
- construction of door (wooden- or metal-framed)
- size of door opening

Length of track
Select the track according to the weight and dimensions of the door. As a general rule, twice the width of the door is needed. Once the track has been selected, the accessories should be chosen from the same product system (e.g. wall brackets SK-150 for a K-150 track).

Attaching the track
The track should be attached with brackets selected according to the method of attachment (wall/ceiling). The capacities quoted apply only if brackets are used. In the lightweight series (under 100 kg) the track can also be fixed directly with screws to the ceiling. The number of brackets is equivalent to the number of meters of track + 1 unit. This gives 1 mt. between brackets. For doors weighing over 500 kg brackets should be attached at intervals of 0.5 metre. Joint brackets should be used at track junctions.

Two hangers required per door
Two hangers are needed for each door. If more are used the door will not work correctly. Note that hangers for wooden and metal doors are of different design, (see wooden door PPS hanger models and metal door MPS hanger models).

Stops limit the door’s movement
A stop should be installed inside each end of the track. Wall stops are fixed to the wall about halfway up the height of the door. Where double tracks are used, track stops should also be fitted.

End clips
End clips prevent tracks moving in their brackets and also provide an attractive finish.

Choosing a bottom guide
A bottom guide ensures faultless and safe operation of the door and also prevents the door from swinging. Bottom guide track AOK is fixed to the bottom of the door. Bottom guide AO-12 (Ø19 mm) is used to steady the door against e.g. a wall. With bottom guide AO-13 (Ø 30 mm) a 40 mm U profile is used as a bottom guide rail. With bottom guide AO-14 (Ø 40 mm) the U profile is 50 mm. Bottom guides AO-22, AO-23 and AO-24 are intended for double track arrangements.

Double track arrangement
Where there is insufficient lateral space for opening the doors, or they are to overlap when opening, a double track arrangement can be used. The length of the tracks is normally twice the width of the door opening. Double track brackets should be attached at 1 mt. intervals. The number of brackets is equivalent to half of the number of meters of track + 1 unit.
