Kupo Adjustable Junior Side Arm (KCP-819)

Overview

The Kupo KCP-819 Adjustable Junior Side Arm is a heavy-duty professional rigging arm designed for offsetting large lighting fixtures or boom setups from a stand while keeping the floor area clear in film, television, photography, and studio environments.

It features a quick-release adjustable clamp system that allows it to be mounted on tubes ranging from 25–55 mm, and it can be positioned anywhere along its 410 mm (16.1") extension length. This gives full flexibility to place lighting or accessories exactly where needed without repositioning the stand itself.

At the end of the arm, it uses a twin 28 mm (junior) receiver system, allowing secure mounting of heavier lighting fixtures or accessories with standard junior spigots. The arm is also equipped with a PUSH & LOCK quick-action mechanism, making setup and adjustments faster and more secure on set.

For safety, it includes a secondary locking pin system, ensuring the arm remains secure even if the primary lock is loosened. Its construction combines high-strength aluminium alloy and steel components for durability under professional load conditions.

It supports up to 40 kg (reduced to 20 kg at full extension) depending on configuration, making it suitable for demanding lighting setups.
