If the two direct fixing walls are not suitable for wall to wall fixing method 1, (i.e. Stud Walls), the opposing walls can be used as fixing points, (assuming they are solid).

The wall to wall fixing method is used when the ceiling is not suitable for fixing the track system, where the track system cannot be fixed to the ceiling at any point A wall to wall installation can be fitted in a in a straight line or in a diagonal direction as long as the fixings remain level. The wall to wall fixing method 2 requires a different type of wall bracket to the standard method. See the diagram below for reference.

The wall to wall fixing method 2 will use steel supporting wall brackets, which will allow a steel box section to be spanned between the two parallel walls. The box section can then be used as a direct fixing point for the ceiling track to span in the required direction, the track will then be supported by another steel box section at the opposing end.

The section below will give full instruction on the recommended method of installation for a ceiling track system into a wall fixing when the standard wall to wall fixing method is not suitable.

A full assessment should have been conducted to ensure that the wall is safe for installation, but the installation engineer must always be vigilant and ensure that the track fixing locations are safe, any signs of cracking, or any other damage to the wall should be avoided. Depending on the type of wall material, the various fixing methods must be followed.

For ceiling track wall fixings, only solid walls are suitable for installation. This includes brick and block materials. To ensure the wall material is suitable, drill a small hole (7mm) where the wall bracket is to be fitted to check the material of the wall. A wall to wall fixing cannot be fixed directly above a door or window as the fixing cannot be fixed to a lintel. This will not be a sufficient fixing point to bear the load of a ceiling track system.

5.2.1 Aligning a Wall to Wall Fixing Method 2 onto the Walls

When a track system is installed onto a wall fixing or a wall to wall fixing, it is essential to ensure that the track system is level to ensure that the fixings will align. The wall to wall fixing method 2 includes four wall fixings that must be aligned horizontally. Follow the guidance below:

1. Measure the distance between the two fixing walls.
2. The steel box sections must be cut to suitable length, this will be the distance between the two walls subtracting 20mm.
3. Determine the spanning requirements of the track system and choose a suitable track type for the installation at hand. See section 1.1 for maximum track spans.
4. Along the full length of the track installation, any obstacles must be avoided, this includes obstacles such as light fixings, sprinklers etc. To accommodate this, the wall fixings maximum height should be 50mm below the lowest obstacle on the ceiling. This will also provide a clearance gap for the track bracket fixings above the wall bracket upper face.
5. Determine a suitable location for the first wall bracket fixing. Align the wall bracket as close to the ceiling as possible to provide maximum track height. Depending on the wall type, the bracket must
never be fixed to the top two bricks, as this will not provide sufficient strength to support the track system, always ensure that the fixing point is secure.
6. Place the wall bracket onto the wall and mark out all the hole fixings onto the wall with a marker/pencil. See diagram below for hole positions.
7. Using a laser, the second bracket position can be marked on the opposing wall to provide a level fixing.
8. Using the laser and a tape measure, position the third and fourth wall fixing on the wall, and mark out the fixing positions.

5.2.2 Fixing the Wall to Wall Fixing Method 2 to the Walls

To fix the wall to wall fixing method 2, the fixing method must be split into sections, this includes fixing the steel wall brackets, the steel box section and the saddle brackets with the track. See the guidance below for the correct method of fixing. Ensure to first refer to section 5.2.1 for the correct alignment and marking out positions of the wall brackets.

Steel Wall Bracket Fixing

When fixing the wall bracket to the wall, the best fixing method is to fix threaded bar directly into the wall through the process of chemical resin. There will be three fixings to support the wall bracket, and the threaded bar must be inserted a minimum of 70mm to provide suitable strength to support the ceiling track. The wall bracket must be installed into a wall that is in good condition, ensuring that there are no cracks or weaknesses found during placement.

When using the chemical resin, always ensure to follow the manufacturer’s instructions along with the guidance of this manual.

1. Align the steel wall bracket up against the wall to ensure the pre-marked hole positions remain true.
2. As the wall is solid concrete or similar block material, drill the three marked holes to a minimum depth of 70mm, this depth provides suitable strength for the fixing to support the track. A 16mm drill bit diameter should be used.
3. Once the holes have been drilled, they must be cleaned out, a hoover, air gun or hole brush will suffice.
4. Ensure the drilled hole positions remain true.
5. M12 threaded bar should be cut to allow a minimum of 70mm insertion into the wall along with an additional 20mm to allow for the wall bracket and fixings. Three M12 threaded bar are required for each wall bracket.
6. The chemical resin can be placed into the gun and tested to ensure the two resins are mixing correctly. The two resins are individually coloured white and light grey, but when dispensing the resin out of its nozzle, they should mix into a dark grey colour. Ensure that this is the colour of the resin.
7. Inject the holes with the chemical resin, the resin should fill 50% of the hole capacity.
8. Insert the three pieces of threaded bar into the holes. This will force the resin to fill the full holes capacity.
9. It is highly recommended that the threaded bars are twisted into the holes to provide additional strength and mixing with the chemical resin.
10. Place the steel wall bracket onto the threaded bars.
11. Place a M12 washer and M12 nyloc nut onto the threaded bars and tighten onto the wall bracket for secure fixing.
12. Repeat these steps to secure all four steel wall brackets. The wall brackets must be fitted directly opposite to each other for a level track fixing.
13. Allow each fixing time for the chemical resin to cure, see manufacturers curing times in the table in section 1.4.

Wall to Wall Fixing Method 2 – Assembly

The steel box section is spanned between the two walls and is fixed directly onto the steel wall brackets, this box section provides a fixing point for the saddle bracket and track.

The box section will require being cut to length to suit the spanning distance of the room. Follow the guidance below on how to attach the box section to the steel wall brackets correctly.

1. Position the steel box section into the steel wall brackets vertically. (as shown in the image).
2. From here, the hole positions on the steel box section can be determined and marked.
3. Drill a 13.5mm clearance hole to allow the fixings to pass through the box section at both ends.
4. From the centre point of the box section, a 13.5mm clearance hole must be drilled into the side face for the saddle bracket fixing.
5. Reposition the box section onto the wall brackets and secure using an M12x120 bolt, ensure to place a washer at either end and secure using an M12 nyloc nut.
6. Repeat this process for both box sections onto all four wall brackets.
7. Position the saddle bracket centrally onto the box section and align with the predrilled clearance hole.
8. Secure the saddle bracket onto the box section using an M12x75mm bolt, ensure to place a washer at either end and secure using an M12 nyloc nut.
9. Attach a track bracket onto the saddle bracket using an M12x25mm bolt, ensure to place a washer between the bolt head and saddle bracket, and secure the track bracket using a single half nut. Apply loctite 270 to the end of the bolt to secure the nut.
