The ProMaster 5521 heavy duty flex arm is an all-purpose helping-hand for a photographer while shooting. And it can handle a heavier load than ProMaster’s 5514 ‘standard’ flex arm. It connects to a variety of clamps, tripods, and other grip items so you can hold and maneuver a light, flash, reflector, monitor, or other accessory to aid in your photography and videography.

Henry ★★★★★

I’ve been using this to hold a wireless flash trigger in tight spaces, and the knurled locking knobs actually stay tight under vibration. The extra weight capacity over the standard model made a real difference when I added a small modifier.

Mia Y. ★★★★★

I was amazed how easily it locked into position with my 24-70mm lens attached. The metal knobs feel solid and the grip is much better than the standard version I tried before.

Hannah M. ★★★★★

Finally a flex arm that doesn't sag under my larger LED panel. The heavy-duty build really lives up to its name, and the grip is solid on my light stand.
