The Manfrotto 203 Mini Extension Arm is a compact, robust aluminium extension designed to work seamlessly with the Manfrotto Mini Clamp 171. Measuring just 12 cm long and weighing only 150 g, this black-finished arm includes a standard 013 double-ended spigot and provides a secure 5 kg payload capacity, making it ideal for adding extra reach to lights, cameras, monitors or accessories in tight spaces or on small supports.

Manfrotto 203 adds a rigid 12 cm extension to a compatible support. The aluminium arm weighs 150 g, supports up to 5 kg and includes a reversible 013 spigot.
The 203 fits the Mini Clamp 171 socket. The mounting view shows this connection; the clamp is sold separately. Check every attachment before loading the assembly.

The 203 fits the Mini Clamp 171 socket. Length: 12 cm.

A short, rigid extension helps position a compatible light, camera, monitor, microphone or accessory in confined spaces without adding an articulated joint. The black aluminium arm is easy to mount and remove, and the included 013 spigot provides a 16 mm mounting surface with male 1/4″-20 and 3/8″-16 threads at opposite ends.
Use the threaded end and stud orientation required by the attached equipment. The arm's 5 kg rating does not increase the capacity of its clamp, adapter or support: keep the complete load within the lowest limit. The photographed Mini Clamp 171 is not included.
Manfrotto 042 offers 19.5 cm reach and an 8 kg arm rating, but uses a Super Clamp base rather than the 203 / Mini Clamp 171 connection. It is a conditional alternative, not a direct replacement or variant.
