Overview

The KUPO CB-22 is a RIGPRO chain bag sized for 40 m of 7.1 mm load chain, keeping excess hoist chain contained above the work area instead of hanging loose from the hoist body. Its rectangular metal upper frame, 1000 denier black woven fabric, reinforced bottom, and included hoist attachment hardware make it a practical safety accessory for professional overhead lifting setups.

Why It Matters

CB-22 is for longer tour and arena chain runs where a mid-size bag runs out of room. It keeps a large amount of spare chain controlled while staying smaller than the 36" bag used for the longest drops.

Key Features

• 14 x 25 cm metal upper frame keeps the bag opening shaped and easy to attach near the hoist body.
• 56 cm, 22" bag height provides capacity for 40 m of 7.1 mm load chain while respecting the 75 % bag-space guideline.
• 8 mm acrylic bottom plate and three 3.5 cm polyester bottom straps distribute chain weight across the bag base.
• Two lower drain holes help prevent rainwater buildup when the bag is used in outdoor or weather-exposed rigs.

Additional Technical Notes

• Bottom Straps: 3 x 3.5 cm wide polyester straps, crisscross pattern
• Included Hardware: 2 eyehooks WLL 340 kg and 2 quick-link carabiners WLL 997 kg
• Safety Note: Hook block or load must not contact bag during operation
