Pure triangles are the strongest shapes in structural engineering and hollow tubes are the most efficient profiles in terms of weight vs rigidity. Therefore combinations of these two are always best wherever maximum strength and minimum weight is required.
In roof racks, subject to dynamic forces and continuous movement this is particularly important as it provides maximum fatigue resistance and crossbar support, especially in long, cantilevered, over-cab racks.
Combined with double bolted joints and specialised MIG welding techniques you get the best power-to-weight ratio and robustness of any mass produced, adjustable contractors rack.

The LOW PROFILE OPTION
Same great heavy duty robustness and features of a TrelliRack, but with a squared off, lower profile side-frame (just 100mm high). Very neat, especially on panel vans and half-tonners, with better underground parking clearance. So your real decision is simply whether to “Go HIGH or Go LOW”!
