Installation & Warranty (Receiver Adapter)

We use the standard frame mounted hitch to flat tow a car behind our motorhome. I added this to the top of motorhome square tube bumper to attach a bike rack. Works very well. I wouldn't use it to tow a car or trailer over 1000 lbs. This part would probably hold up but it would likely tear the bumper off! - DT
I put this on my Kubota tractor for hauling trailers and other hitch ball vehicles. It is a first rate product and I recommend it. - PR
Perfect for my bumper and will be used for flagpole holder and for rear travel rack. Fit perfectly on the bumper with no modifications and took 5 minutes to install. Do not plan on overloading this as weight limit is 200 lbs, but for light duty this was a much less expensive and easy fix versus installing a frame mounted hitch or paying twice as much for a more heavy duty bumper mount hitch. - DD
Very impressed. There were a few of these adapters that were cheaper, and many that were more expensive. This one is very rugged. Certainly, much more rugged than my RV trailer bumper. Fit perfectly. Welds look smooth and strong. Finish is nice. Certainly worth 5 stars - JB
The instructions on this product were very easy to follow and it went on quickly on the bumper of my camper. I used it for a carrier that we load with bundles of wood and it held it just fine. Great product!!!! - SS
