Audak 1 Pair Aluminum Mounting Bracket Kit Tube Clamp for 2.5 Inch Bullbar Roof Rack Roll Cage Horizontal Bar

These are very well built and sturdy. Actually over engineered for my intended use.

Clamp is strong, but the rubber sizes may be slightly thin. I fully clamped with the 1.375in rubber settings on a motorcycle front fork and it slipped quite easily. Needs better design. Quality is good though. But can easily mess up threads if clamp is not aligned enough. This design is not a good design in my opnion, but for light applications, it will do just fine.

Brackets seem sturdy and well made but as they are received they will not hold a flag pole such as a dune flag. You must drill the hole out to allow the shaft of a dune flag fitting to mount through it

So many options and I think these were a good choice. Plenty out there cover many bar sides over a much wider range than this set. I feel this set with multiple sizes of rubber shims over a narrower size range allows for more precise fine tuning. No spin! Please note the security screws/bolts pictured are a separate purchase and do not come with this product.
