Fixed suspended ceiling
In case of a fixed suspended ceiling, the rail installation is carried out in two steps. Therefore, the lowering bracket
needs to be secured without the support from the ceiling bracket.
1. Concrete ceiling.
2. Expansion bolts M8x75, 2 pcs.
3. Yokes, (Steel plate for even installation surface), 2 pcs. 3mm.
4. M8 nuts, 6 pcs.
5. M8 coupling nuts, 2 pcs.
6. M8 locking nuts, 2 pcs.
7. Aluminium pipes Ø40, 2 pcs.
8. Distance pipes Ø20 (or nuts and washers), 2 pcs.
9. Ceiling bracket (standard), 1 pcs.
10. Suspended ceiling.
11. M8 threaded rods, 2 pcs.
12. Locking washers, 2 pcs.
(A HKD anchor can be used as an alternative, which the rods are fixed directly into).
Cut the pendle bracket pipe to a length equalling the distance measured between the concrete ceiling and the
lower face of the suspended ceiling minus 50 mm.
This length is appropriate for a double gypsum layer in the ceiling and an extra allowance of 12 mm.
Cut the threaded rod to a length equalling the distance between the concrete ceiling and the lower face of the
suspended ceiling minus 10 mm.
When installing, first install the top yoke for the centre bracket of the rail, install the yoke as described in the
installation instructions for direct installation in a concrete ceiling. In this case, however, drill both holes for the
expansion bolts at the same time.
When driving in the expansion bolts, leave approx. 15 mm to protruding below the nut, so that you can screw the
coupling nut onto it to its half length. Counter-tighten the coupling nut against the expansion bolt nut.
Attach a nut approx. 20 mm onto the threaded rod and screw the threaded rod into the coupling nut, until it
touches the expansion bolt, and counter-tighten the nut.
Attach the bottom yoke and secure it with nuts.
Note! Avoid paint on the bottom section of the threaded rods until the installation is complete.
Prepare the rest of the installation points after a careful and accurate measuring.
First step of the installation is now complete and the construction of the suspended ceiling can be completed.
In the final installation, position the distance pipe in the suspended ceiling. This pipe will protect the suspended
ceiling. Cut the distance pipe to a length creating a distance of 1-5 mm between the lower face of the suspended
ceiling and the upper face of the installation bracket; instead of pipes, nuts and washers can be used to ensure the
recommended distance.
