The first thing I noticed looking at the boxes is this rack is, contrary to one of the reviews below, made in China. Not a huge deal, but in comparison the R3 is made in the US. I saw some fit and finish issues, which I will detail below, which I'm guessing are attributable to being made in China.
Once I unboxed everything, I was a little puzzled that there were no instructions of any kind. There were over 20 pieces, 36 bolts of three different lengths, 36 nuts, and 72 washers. I called Fringe on the phone the next day and explained I had ordered and they must have not packed the instructions. They response: there are none and that I should 'look at the photos on the site'. As you can see above, there are only three of four, relatively low res pics that only give you so much insight. I find that totally unacceptable. Sur
There is plenty of depth with it to not feel closed in during squatting etc. Safety bars are easy to move. Simple, solid and gets the job done without a concern from me.
PS - as always the customer service was fantastic. There were 3 washers and 1 nut lost in getting to me. As soon as I reached out to Fringe, the replacements were out the door in minutes. Great company!
That should be compatible with any 2x3 rig. I hope this helps. Please don't hesitate to contact us if you have any other questions or concerns. Thanks!
