The Matthews 40" Extension Arm with Hollywood Grip is a professional-grade mounting and positioning tool designed for the film, television, and photography industries. Its primary function is to extend the reach and versatility of standard light stands, C-stands, or wall mounts, allowing cinematographers and gaffers to precisely position lighting fixtures, flags, nets, or small cameras in hard-to-reach locations. The arm itself is a rigid, heavy-duty aluminum tube, typically 40 inches in length, that serves as a cantilevered beam. One end attaches securely to a stand via a specialized "Hollywood" or "grip head," a versatile and robust clamping mechanism renowned for its strength and precise adjustability.

The Hollywood Grip head is the critical component of this system. It is a large, knurled metal clamp that can securely hold the extension arm at any angle. Its design features two independent locking mechanisms: a large central knob that controls the main jaw pressure on the arm, and a separate knob that controls a pinching action for finer rotational adjustment. This dual-locking system allows the user to quickly make coarse positioning adjustments and then lock everything down with exceptional rigidity, preventing any slippage or "creeping" under the weight of heavy lighting equipment. The grip head typically includes a 5/8" baby pin receiver on its body, allowing it to be mounted directly onto a stand, and often features additional 5/8" pin holes for attaching accessory arms or mounting multiple items.

Constructed from durable, lightweight aluminum, the entire assembly is built to withstand the demands of a professional set while remaining portable. The combination of the long arm and the versatile grip head enables countless creative setups: hanging a light just outside the frame, extending a flag to create a shadow, or positioning a monitor for the director. It is an indispensable piece of grip equipment that provides a safe, stable, and infinitely adjustable solution for manipulating equipment in three-dimensional space, greatly enhancing the control over the lighting and camera environment. The Matthews brand is synonymous with reliability in the industry, making this a trusted tool for achieving precise and repeatable positioning.
