5.5 Rail coupling
5.5.1 Rail coupling for profile M & L
The following items are used for rail coupling:
1. Rail profile M no. 1.
2. Rail profile M no. 2.
3. Insertion tube (for profile M).
4. Coupling bracket (quick or standard).
5. Pipe pins.
6. Stop screws.
7. Bolt M6.
8. Washer.
9. M6 lock nuts.
Push the insertion tube halfway into rail profile no. 1 and secure it with a passing bolt. Furthermore, drill the holes for
the pipe pins in rail profile no. 2 up to Ø3.2mm in a depth corresponding to half the length of the pipe pins.
Drive the pipe pins halfway into rail profile no. 1 and squeeze them together in the end.
Push the coupling bracket halfway onto rail profile no. 1 and secure it with the stop screw.
The coupling bracket is only required when mounting the rail on the ceiling. If you are coupling a traverse rail, the
coupling bracket is not required. Drive together rail profile no.2 and no.1 and secure them with the locking screw
in the coupling bracket and the passing bolt.
Install the coupled rail using the instructions for installation of straight rail profiles, see section 5.2.
When coupling long rails, it can be difficult to lift the coupled rail in one piece. In this case, first install the first rail
on the ceiling. Then lift up the next rail which has been prepared for coupling and push the rails together.
5.5.2 Rail coupling for profile S
The following items are used for rail coupling:
1. Rail profile S no. 1.
2. Rail profile S no 2.
3. Coupling bracket (quick or standard).
4. Pipe pins.
5. Stop screws.
Drill the holes for the pipe pins in rail profile no. 2 up to Ø3.2mm in a depth corresponding to half the length of
the pipe pins.
Drive the pipe pins halfway into rail profile no. 1 and squeeze them together in the end.
Push the coupling bracket halfway onto rail profile no. 1 and secure it with the stop screw.
Insert rail profile no. 2 into the coupling bracket and drive the two rails together.
Tighten the stop screw on rail profile no.2.
Install the coupled rails using the instructions for installation of straight rail profiles.
When coupling long rails, it can be difficult to lift up the coupled rail in one piece. In this case, first
install the first rail on the ceiling. Then lift the next rail which has been prepared for coupling and
push the rails together.
