Tube Clamp Mounting Bracket, KMFCDAE Roll Bar Clamps for 1.5 Inch Tube Roll Cage Bull Bar Roof Rack LED Light Bar Mount (Adjustable, 1 Pair)

These clamps can be found here: https://a.co/d/0daMdQnhAnd the two threaded rods came with the desk mount in the R3/R5 bundle. They have the same diameter of M8 bolts, therefore fit perfectly with the same nuts and washers included. Everything is tightened with no room for mistakes. These clamps are hit or miss even though they seem quite solid, I’m just not sure if they can withstand the weight of a handbrake, when I decide to buy one. I’ll be sure to come back in the near future, for more feedback.
