Even distribution on the rain gutter using load/cross bars

[alia176]

I'm looking for a way to evenly distribute the weight from using cross bar tower onto the rain gutters. Currently, there is a Columbus RTT on three Thule cross bars and short towers. Does anyone make something that touches all three towers with a rounded bottom? Some of the roof rack manufacturers are doing this in order to save the rain gutters.

Thanks.

I don't see how touching all three risers will help unless the material is very rigid. Anything that has even a little flex is only going to distribute the load a few degrees to each side depending on how tall it is. My point is three trapezoidal pieces would probably be as good as one long piece.

Yeah, good point. I thought I saw a rigid member connecting all the towers, just can't recall where that was. I might have to fabricate something similar to the Prinsu rack design, PrInSu Design Studio - 80 series roof rack

Perhaps incorporate the 80/20 bars into some type of Alum side rails.

The PrInSu design uses some pretty thick looking material. It looks cool to. You would get better force distribution with more cross sections connecting the rail to the rack.

Diamondrax makes trapezoidal plates to add to their mounts, may work with others, not sure.

My current mounts aren't the best fitting so I'd like to see a thin steel bar shaped to the 80's gutter that could go under all three towers.
