Manfrotto 66 Double Female Stud - Super Clamp Adapter

The Manfrotto 066 Double Female Stud is a compact mounting adapter designed to expand the rigging options on any Manfrotto Super Clamp. It provides two female threaded receivers — one at 1/4"-20 and one at 3/8" — allowing you to attach a wide variety of photographic and video accessories that use standard tripod threading. Whether you need to mount a monitor, articulating arm, or light accessory, this stud gives you a secure, threaded connection point wherever a Super Clamp can grip.

Machined from solid brass, the 066 is built to withstand repeated tightening cycles without stripping or deforming. At just 0.06 lbs, it adds negligible weight to your setup. It serves as the direct replacement for the older Manfrotto 3113, maintaining the same dimensions and thread specifications. For anyone building out grip rigs with Super Clamps, this small adapter is an essential connector that bridges the gap between clamp and gear.
