Customer Reviews (4.6 / 5 · 5 reviews)

William ★★★★★

I was pleasantly surprised by how snugly this fits on the 1.25" shaft—no wobble at all. It gives me peace of mind knowing the counterweight is securely locked in place during a long imaging session.

Carter ★★★★★

The threads on this washer are cut cleanly and it fits snugly against the shaft without any wobble. Gives me real peace of mind knowing the counterweight has that extra layer of security. Exactly what I needed for my setup.

Ella T. ★★★★★

Installed this on my 1.25" shaft and it snugged right up against the stop ring, no wobble. The 5/16 x 1.5" dimensions are precise enough that it doesn't slide around during setup. Feels solid.
