Kupo Junior Boom Stand (546M)

Overview

The Kupo Junior Boom Stand (546M) is a professional heavy-duty convertible lighting stand designed for film, television, studio, and commercial production environments. Built from durable chrome-plated steel, it functions both as a standard lighting stand and a fully integrated junior boom arm, making it an extremely versatile support solution for medium-sized lighting fixtures.

The stand is engineered for flexibility on set, allowing operators to quickly convert it from vertical stand mode into a boom configuration by sliding out the centre column and positioning it via the pivoting collar system. This makes it ideal for overhead lighting, hair lights, backlights, and softbox setups where precise positioning is required.

With a load capacity of up to 30 kg in stand mode and up to 8 kg at full boom extension, the 546M delivers reliable support across a wide range of production scenarios. Its reinforced steel construction, wide footprint, and integrated levelling leg ensure stability even on uneven terrain.

A universal combo top provides compatibility with both Junior (1-1/8") and Baby (5/8") fittings, while optional caster compatibility allows for smooth repositioning on studio floors. Designed with durability and workflow efficiency in mind, this stand is a trusted solution for professional lighting crews.
