Isabella ★★★★★ Oct 21, 2026

Picked one up to connect a light stand adapter to a microphone boom arm, both sides threaded on perfectly with no wobble. The brass feels noticeably durable compared to the aluminum adapters I've used before.

Hazel ★★★★★ Oct 20, 2026

Needed a solid brass coupler for a flash bracket and this did the trick. The threads cut clean and tight on both the 1/4-20 and 3/8 sides.

Harper ★★★★★ Oct 19, 2026

The double spigot solved my adapter problem instantly—having both 1/4-20 and 3/8 threads on one solid brass piece means I don't need to carry a drawer full of converters anymore. Threads cut clean and mate snugly with no wobble. Fit my light stand and ball head perfectly right out of the box.
