The Hejnar Photo F61b Quick Release Clamp is a precision-engineered Arca-Swiss compatible clamp designed for modular tripod setups and nodal slide integration. With a 1.5" jaw length and dual mounting options (1/4"-20 screw or 3/8"-16 post), it offers secure, flexible attachment for a wide range of support systems.
Combine this clamp with Hejnar nodal slide base rails to create a rail with integrated clamp. Two clamps can be joined using optional aligning pins and bushings (sold separately) in multiple orientations. Pins prevent twisting, though knobs must face opposite directions when assembled. When disassembled, each clamp functions as a standard Arca-Swiss unit.
The captive knob design ensures the knob stops at maximum opening and cannot be lost in the field. A metric scale engraved in 1mm increments supports precise positioning. Built from CNC-machined 6061-T6 aluminum with stainless steel hardware and a black hard coat anodized finish.
