Extension Arm for Lighting & Studio

The Manfrotto 042 Extension Arm with 3094 Stud is a compact support tool for photographers and videographers. It measures 7.6 inches in length and provides adjustable positioning for lights, flags and reflectors. The arm integrates directly with the Super Clamp 2915 for secure mounting. It suits creators needing precise, short-reach placement in studio or location setups.

Brass and Steel Construction with 3094 Stud

The arm is crafted from durable brass and steel for long-lasting performance and reliability. A 3094 stud is included, offering a standard connection point compatible with a wide range of studio accessories. This stud allows quick attachment of lighting fixtures or modifiers without additional adapters. The robust metal build resists wear during frequent repositioning and transport.

Fixed 7.6 Inch Reach and Single Stud Interface

The extension length is fixed at 7.6 inches, limiting the distance you can offset equipment from the clamp. Only one 3094 stud is provided, so the arm supports a single accessory at a time. It does not offer telescoping or multi-angle joints beyond the clamp’s own adjustment. Users requiring longer reach or multiple simultaneous mounts will need additional arms or different hardware.

Questions about this item

What thread does the 3094 stud use and what can it mount?

The 3094 stud provides a standard mounting point for lights, flags, reflectors and similar accessories that accept its thread.

What clamp does the 7.6-inch arm connect to and how is it secured?

The arm integrates with the Super Clamp 2915, which clamps to a pole or surface and locks the arm in place with its tightening knob.

How do you assemble the arm, stud and clamp, and what step is often missed?

Thread the 3094 stud into the arm, insert the arm into the Super Clamp 2915, then fully tighten the clamp knob; the step often missed is securing the clamp before adding any load.
