Question:

Hello, Im looking for a platform rack to mount to a pair of 1.5 square steel crossbars, 60 wide that are spaced 42 apart. This is for a custom built offroad trailer. Please suggest a few alternatives. Thank you.

Hey Michael, so we have larger platform racks like the Rhino Rack Pioneer Platform part # RR99AP which is 83 inches long by 56 inches wide but we don't have hardware to attach it to a square crossbar as big as what you have. There might be an easier solution elsewhere but our best option would be a platform like this with a fabricated set of hardware for your bars. I wish we had an easier solution.

Just to be clear, I'm not terribly concerned about the size of the platform I just need something that can mount to 1.5 inch square crossbars. It doesn't have to be a Rhino Rack platform.

@MichaelE That makes sense. We just don't have any great options at all that can fit that bar size since 1.5 inch square is taller than most roof rack bars.
