Track cut length
A (from the upper point to the floor in mm) less
B (track reduction from the point)
equals C (total track cut length)
For example:
Dimension A = 3250mm
Angle = 45°
3250 - 74 = 3176

How to obtain a standard finish:
SlideTrack was designed to end with the platform
aligned vertically to the distance from the point, as
shown in figure 12.
This end position can be changed to shorten the
height of platform landing at the top of the staircase,
consequently moving the upper limit ramps downwards
towards the track. In addition, this will create lateral
play between the platform edge and the distance from
the point.
We recommend keeping this play to a minimum,
preferably less than 50 mm.
It may not always be possible to reach intrusion less
than absolute zero when SlideTrack is in a completely
high position. The lower intrusion is regulated by the
staircase angle and by the height of the first riser.
In general the smaller the first riser (D) is, the less the
lower track (F) intrusion will be; and the steeper the
angle, the less the lower intrusion (F) will be.
In most applications, less than zero intrusion is not
necessary since the door lintel (door frame) is normally
at the end of the first point. It is usually 20mm broad. In
this situation SlideTrack can be adapted with a real zero
track intrusion which meets the obstacle elimination
requirement from the entrance door below.
