Our unique Three-bolt Lock design makes it compatible to most van rain gutters; while keeping the stability for the loads, it is easy to install & uninstall.
The Protective Rubber Covers on both upright clamps prevent metallic friction on the rain gutters, which can also further reduce chance of rusting.
The adjustable middle bar of model X27 is built with the thickness of 1.5mm steel tube and 2mm actual thickness of steel plates are used on both side.
The X27 also comes with four Adjustable Ladder Stoppers; (two for each bar), they provide the convenience and security for multiple ladder carrying.
The Oval Shape design of the upright clamps is Height-reduced, ( less than 11″ while installed ); this design not only prevents water leakage & improves wind noise problems, it also makes your vehicle more accessible to most height restrictions.
