PM Flex Arm HD (Heavy Duty)

The knuckle joints hold my setup rock-solid even after a week of constant repositioning, and the tightening collar hasn't loosened once. Solid buy for a cage rig, though I wish the included bolts were slightly longer for thicker frame bars.

I was worried about my heavier gear sagging, but this arm holds everything rock-solid without any droop. The thick metal construction feels like it could withstand a lot of daily use.

The adjustable tension knobs let me dial in exactly the right amount of resistance, and it holds my heavy cage steady even during intense use. Setup was straightforward and it feels rock-solid on my desk.
