When you're shopping for a truck bed cover rack, look no further than the STR soft tonneau cover rack. It adds together all the ingenuity of a soft tonneau cover with that of a heavy duty pickup bed rack. Want more storage capacity? How about adding the versatility of 300 pound capacity to your truck bed? Haul ladders, pipes, tubing, lumber and more while keeping the items under your tonneau safe and secure from the elements.

The STR truck bed rack system is perfect for contractors and for general use as well. The design allows for easy access. Just roll up your tonneau cover to get at your cargo. No need to remove the rack or your top load. If you do want to remove the STR, it can be adjusted forward or taken off the truck bed entirely in seconds. No hassle!

It is built to handle the long haul. Made from aluminum, the rack is coated with a black powder-coat finish to match and accentuate your truck's design. The construction is made with stainless steel hardware to prevent against rust and corrosion long term.

The STR soft tonneau cover rack is compatible with all of ProRac's products, including the ski and snow board carriers, bike rack, tie downs, kayak and canoe watersports carrier, and more.

Ease of Installation
The ProRac tonneau rack uses first-rate materials like stainless fasteners, and precision extrusions. It goes together very easily and is plenty strong. You can also bolt onto it pretty much whatever you want, and easily reconfigure it - I have a combination of 4 bike racks and/or a cargo box, plus hooks for a canopy when I'm parked at a race. Plus, it's not too high to manage loading/unloading.
I did have 2 minor things, though: I didn't much care for their tear-drop seal kit - it did not fit well in the corners of the bed. Something more like closed-cell foam blocks work better on my truck with the Truxedo Truxport tonneau cover (which is listed as compatible); the other thing is that the bed rails are wider than my Colorado bed sides, so they hang off a little bit, even with the narrowest set-up. This doesn't affect how much it can carry, but it just doesn't look as "clean" as I had imagined, and it is at least a 1/2" wider than the tonneau cover on each side, so a closer fit would be preferred, but it works just fine and still looks pretty good.
