GM100 5.5" Universal Roof Rack Gutter Mount Adapter - Heavy Duty Black Car Roof Rack Clamps for SUVs, Trucks & Vans - Perfect for Camping, Kayaking & Outdoor Adventures

This is the finest-cheapest set of 4 Roof Rack Gutter Mounts available. They can securely hold a lot of weight (I can stand on top of my steel rack and there is no flex) and are easy to assemble.I painted mine with bedliner spray paint and they look great.It was really hard to install the bottom bolt/nut but I think that is just because of the shape of my 98 Montero's roof line. It is very steep and tall compared to most vehicles with a rain gutter so there is hardly any room to get your fingers or a wrench behind the Surco mount to secure it. But I can't fault Surco for that since these are for a universal applications.
