Instructions

These instructions cover the preparation of doors to be
fitted into a pocket that has the CS SofStop Track fitted.

Read through the notes carefully before beginning as
different mounting plate positions and set-ups may be
required for different configurations.

Ensure rear activator is positioned correctly
in the track BEFORE lining the wall.

IMPORTANT

The CS SofStop carriages require a clean track running
surface free of any contamination or damage.

After installation but before lining, clean the full length

of the inside running surface of the track with a soft
rag, then TAPE UP THE TRACK to ensure no dust or
debris enter the track during building works.

Make sure no dirt, grit or aluminum swarf gets into
the track. This could impair the smooth running of the
carriages.

1 Activator positioning

Before mounting the track in the opening you will
need to insert the front and rear activators into the
track. Use the formula (right) to measure from the
notched end of the track to the center of the activator.
Only tighten one screw on the activator as this
is an approximate position. Final position will be
determined later.

If your door protrudes out of the pocket in the open

position you will need to take this distance away
from the rear activator formula.
