Pro media c40 clamp

Good construction, just the right size for my needs. I have a table top Bogen tripod that needed an Arca Swiss clamp that would mate up with my camera L brackets.

I use this to unify all the different tripod release mounts I have. Manfrotto used one, Giottos uses another. Just screw the various quick release onto this and everything is Arca-Swiss style. Well made and seemingly durable.

Explore the robust capabilities of the ProMediaGear C40 Clamp Screw-Knob, a versatile and durable addition to your photography or videography equipment. This high-quality clamp is designed with a 1/4"-20 threaded insert, making it compatible with a wide range of cameras and accessories.

Constructed with a steel, nickel-chrome plated insert, the C40 Clamp Screw-Knob ensures the threads remain in excellent condition for an extended period.

The ProMediaGear C40 Clamp Screw-Knob is finished with a hard black anodized surface coating, providing a matte, non-reflective finish that is resistant to wear. This feature not only enhances the clamp's durability but also its aesthetic appeal.

The clamp also boasts a self-retaining, nickel-chrome plated knob, further enhancing its durability and giving it a sleek, professional look. Whether you're a professional photographer or a videography enthusiast, the ProMediaGear C40 Clamp Screw-Knob is a reliable and sturdy choice for securing your camera or other devices.
