Kupo KCP-819 Adjustable Junior Side Arm

Kupo KCP-819 Adjustable Junior Side Arm – 410mm Offset with Quick-Release Clamp

The Kupo KCP-819 Adjustable Junior Side Arm offsets a boom arm or large lighting fixture from a heavy-duty stand while keeping the floor area unobstructed. It uses a quick-release clamp for fast, secure suspension and positions equipment anywhere along its 16.1" (410 mm) offset length.

Key features and benefits

• Quick release clamp allows fast and secure suspension of a lighting fixture overhead, leaving the floor area unobstructed.
• Patented PUSH & LOCK locking system enables you to ready your lighting fixture effectively and lock it in place.
• Wide rigging range for pipes with diameters from 25 mm to 55 mm, increasing mounting flexibility.
• Clamp body constructed of gravity die-cast aluminum for durability in regular use.
• Attachment uses a twin junior (28 mm) receiver, firmly welded on high-tensile-strength alloy steel, and can be positioned anywhere along the 410 mm offset length quickly and easily.
• Backward safety pin device provides double security in case of accidental loss of the offset arm.

How it mounts and adjusts

The adjustable quick-release coupler fits tube sizes from 25 mm to 50 mm and lets you mount the side arm at any point along the 16.1" (410 mm) length. This design makes it simple to offset a boom or fixture without moving the stand, and it speeds setup and repositioning on set.

Materials and construction

The side arm combines aluminum alloy castings and alloy steel components. The clamp is made from gravity die-cast aluminum for strength and longevity. The twin junior (28 mm) receiver is welded to high-tensile-strength alloy steel for secure attachment of compatible fixtures.

Practical use cases

1. Offset a boom arm to clear the floor when working in tight spaces or on location.
2. Mount larger lighting fixtures away from the stand to achieve specific lighting angles without repositioning the stand base.
3. Quickly rig overhead lights while keeping the working area below free for crew and equipment.
