Shelving that is not properly fixed is not storage, it is cargo. In a hard stop the contents keep moving, and a loaded unit standing on a van floor has enough mass to go through a bulkhead.
What Should Shelving Bolt To?
The van's own mounting points, through a kit made for the model and wheelbase. Manufacturers build mounting rails and reinforced points into the walls and floor for exactly this, and the kits are designed to reach them. Screwing into trim panels or unsupported sheet metal is not a lesser version of that, it is a different thing entirely.
Model and Wheelbase Both Matter
Transit, Sprinter and ProMaster all place their rails differently, and each is offered in several wheelbases that move the spacing again. Kits are usually sold per position as well, so a rear driver side kit is not the same part as a front driver side one.
- Confirm the model, the wheelbase and the roof height before ordering.
- Check whether the kit covers one side or both.
- Front and rear positions often need different kits in the same van.
- Extended wheelbase versions are a separate part number again.
Where Backing Plates Are Needed
Any fastener going through flat panel rather than into a reinforced point needs a backing plate on the far side. Without one, the load concentrates on the few square inches around the bolt and pulls the panel into a cone before it pulls through.
Look at what is behind the panel before you drill anything. Wiring looms, fuel lines and side airbag inflators all run inside van walls, and the curtain airbag in particular is not something to put a self tapper through.
Respect the Shelf Ratings
Shelves are rated, commonly around 300 lb per shelf on folding aluminum units and more on fixed steel. That rating assumes the load is spread across the shelf, not concentrated at one end.
Load heavy items low and toward the middle of the run. A unit loaded heavy at the top is working its top fixings hardest, which is the opposite of what you want, and it raises the centre of gravity of a vehicle that is already tall.
Add a lip or a restraint to any shelf carrying round or rolling items. A shelf rated for the weight will still let a cylinder or a coil of pipe leave it on a roundabout, and the rating says nothing about whether the contents stay put.
Check It Once a Year
Vans flex constantly, and fasteners that were tight on install day will not all be tight a year later. Walk the van once a year with a spanner and check every mounting bolt, then look for shiny witness marks around the feet, which show a unit that has been moving.
Do the same after any incident, however minor. Browse van storage and shelving, or the fitted ranges for Transit, Sprinter and ProMaster.
