Commercial Max Roof Rack Installation for the Renault Master

August 14, 2023

On this article, we show you the step by step guide on how to set up and install a Commercial Max roof rack for the Renault Master van.

1. Place the rail so the back edge of the rails is as far back as possible without crossing the rear door line.
2. Mark the drill points with a marker, using a the rails bolt holes as a guide.
3. Begin drilling using a small drill bit (5.5mm) and drill through the roof, where marked.
4. Enlarge or bore the holes with a larger drill bit (8mm). So the bolts will fit tightly and catch the thread.
5. Silicone the bolt holes.
6. Using a socket tool, tighten the bolts and washers through the rails and into the roof.
7. Tighten unistrut nuts to the rails by hand with the ‘teeth’ side facing down.
8. Use the rack bars to determine the position of the second rail. Repeat the steps until all four rails are secured and tighened on the roof.
9. Lower the rack onto the rails so the unistrut nuts slot into the channels of the rack.
10. Tighten the unistrut nuts by hand, it can be difficult with the mesh but be patient and work through it slowly.
11. Finish tightening the uni-strut nuts with a spanner.
12. Use one hand to hold the spanner in place through the mesh, and the other to tighten.
13. Ensure all unistruts are tightented before completing.
