Overview

The KUPO KSF-30 is the 30 lb loading-weight member of the KSF shot bag family, made for heavier stand and boom setups that need a denser counterweight. It uses 1000D Cordura nylon, a plastic internal liner, 2 mm steel shot, double Velcro closure, a rubberized handle, and an eyelet with spring lock for boom-hook placement.

Why It Matters

When a boom arm starts to reach farther out, a small sandbag can become a gesture rather than real ballast. KSF-30 gives the crew a heavier shot-filled option while still keeping the bag soft enough to drape and place safely around stand hardware.

Key Features

• 30 lb loading weight provides stronger counterbalance for heavier boom and stand setups
• 2 mm steel shot inside a poly inner bag gives dense weight without rigid edges
• Double Velcro closure helps keep the shot contained during handling and transport
• Rubberized handle makes the heavier bag easier to reposition on set
• Eyelet and spring lock support attachment to a boom hook when the setup calls for it

Specifications

KSF-30 is specified by loading weight rather than empty bag weight. A separate tare weight is not specified, so the 30 lb figure is treated as the working loading weight.

• Loading weight: 13.69 kg (30 lb)
• Fill: 2 mm steel balls encapsulated in a poly inner bag
• Closure: double Velcro design
• Handling: rubberized handle
• Attachment: eyelet and spring lock for boom hook use

Applications

Use it for heavier boom arms, large stand bases, long offsets, and production rigs where a 15 lb or 25 lb bag does not provide enough counterweight.

Compatibility

Part of the KSF shot bag family with KSF-15 and KSF-25. Use on stand legs, boom arms, and suitable boom-hook positions rated for the applied load.
