A small adapter that solves a lot of little grip problems.
The ProMaster Double Spigot 1/4"-20 Male to 3/8" Male is a compact solid brass adapter designed for joining photo, video, lighting, and grip accessories with different thread sizes. With a 1/4"-20 male thread on one side and a 3/8" male thread on the other, it gives you a simple way to connect compatible clamps, mounts, light stands, brackets, and studio accessories.
Looking Glass Photo’s Take:
This is the kind of small part that is easy to overlook until you need it. If you work with stands, clamps, lights, arms, or mounting accessories, having a few thread adapters in your kit can save a shoot from becoming unnecessarily frustrating. Solid brass construction also makes this a better choice than cheap mystery-metal adapters when you are connecting gear you actually care about.
Why photographers like the ProMaster Double Spigot
- Double-sided adapter design gives you a 1/4"-20 male thread on one side and a 3/8" male thread on the other.
