Review on Receiver Adapter Accessories Mounting Carriers by Eric Wright

I rarely write reviews and give this product a high rating even though I am currently unable to use it on my trailer. We have a retractable camper trailer with a 1" x 3" bumper (that's C-channel, not solid tube). I took a chance that this product would work and due to its adaptable design (lots of screw holes on the panels) it would work great but after installing the product I found that my bumper just had too much flexibility when twisting had. (with a hitch mounted bike rack) to make it safe. Again, the problem is where I install it, not the product itself. I leave the product to use after adding another beam to add extra rigidity to the bumper. pictured bolted to studs just under 2" (so you can fit this to a bumper that's less than 4"). I love that they used carriage bolts (so I can install them with just an 11/16" wrench) and also added a few other bolts to the design - one to hold the bike rack rigid in the hitch, as well as two from the clasp on the side to keep the product from moving.
