As addition to Gorilla Racks?
Your review: This product is well made and very robust and of good quality. I bought them as additions to Gorilla Racks since I think that Gorilla Racks are no longer in business. While they had the identical specs I did end up with a surprise. The mounting pins fit exactly into the vertical slots but the length of both the front and side supports were 1/2" shorter than those on the Gorilla Racks. I was able to improvise successfully with a little bit of effort.
Pros: solid material and construction
