The Hejnar Photo 2.375" Arca-Swiss Clamp with Integrated Cotton Carrier Hub is a purpose-built quick release clamp designed to engage directly with Cotton Carrier camera holsters (G3 Harness, G2 Scout and other)—no extra adapters or mounts required. Ideal for long lenses with Arca-style feet, this clamp allows seamless transitions between holster carry and tripod/gimbal setups.

When engaged in a harness, the clamp positions the knob perpendicular to the lens axis for ergonomic access. The integrated hub eliminates length and balance limitations when switching from holster to Arca clamp. Built for rugged field use, it features a tongue-in-pocket design for jaw alignment and internal protection, plus a 2.6mm relief groove to prevent free fall when used with safety-stop-equipped plates.
