ProMaster Articulating Arm & Clamp

ProMaster Articulating Arm & Clamp
Versatile All-Metal Accessory Support – Dual Ball-Joint Arm, Adjustable Clamp & 1/4″-20 Mount

The ProMaster Articulating Arm & Clamp provides a strong, flexible mounting solution for securing camera accessories to flat edges, such as tables and shelves, or round objects like tripod legs and light stand columns. Engineered with durable all-metal construction, the clamp features protective soft pads that maximize grip while preventing surface scratches.

Designed for rapid adjustment, the arm features a single locking knob that simultaneously locks or releases both ball joints for effortless positioning at virtually any angle. The integrated ball head is topped with a standard 1/4″-20 threaded post—supported by a textured grip pad—to securely mount monitors, lights, audio gear, or other field accessories. Additionally, the clamp body includes built-in 1/4″-20 and 3/8″-16 threaded ports for expanding your rig with extra mounting options.
