Hejnar F562b Quick Release Clamp – 2.375" Screw-Knob, Arca-Swiss Compatible

The Hejnar Photo F562b Quick Release Clamp is a precision-engineered Arca-Swiss compatible clamp designed for secure tripod mounting. With a 2.375" jaw length and a 3/8-16 screw mount, it’s ideal for pairing with Arca-style ball heads and plates.

The clamp features 2.6mm deep relief grooves for compatibility with safety stop-equipped rails and a captive knob that stops at maximum opening—ensuring it won’t detach in the field. The knob is machined from a single piece of aluminum with no spacers or bushings, keeping dust and grit out.

The tongue-in-pocket design maintains jaw alignment and protects internal components, eliminating bending forces on the threaded stud. Built from CNC-machined 6061-T6 aluminum with stainless steel hardware and a black hard coat anodized finish.

✅ Compatible With

Markins, Really Right Stuff (RRS), Arca Swiss, Wimberley, Kirk, Photo Clam, Foba, Vanguard ABH Series, Custom Brackets, Jobu Designs, Acratech, and other Arca-style systems.
