Overview
The KUPO CB-C13 is a round chain bag for manual chain blocks, built from 1000 denier textile fabric with a heavy-duty hook and a reinforced round frame. Its 33 cm deep container provides a large compartment for chain storage, while the flat bottom and drain holes help keep the chain supported and drier during practical rigging use.
Why It Matters
Manual chain blocks still create loose chain that needs a home. CB-C13 gives that chain a dedicated bag with a 250 mm steel main frame, stitched support straps, and a wood bottom plate, reducing clutter and helping crews keep the working area cleaner.
Key Features
- 250 mm diameter main frame is welded from 12 mm steel rod for a strong round opening.
- 9 mm wood bottom plate helps distribute chain weight evenly across the bag base.
- 33 cm container depth and 20 kg load capacity suit manual chain block chain storage.
- Galvanized 7/16" drop-forged carbon steel snap hook is rated WLL 750 kg.
Additional Technical Notes
- Hook: 7/16 in galvanized drop-forged carbon steel snap hook, WLL 750 kg
Applications
Use with manual chain blocks in theatres, workshops, venues, touring prep, and temporary rigging positions where hand-chain storage needs to stay controlled.
Compatibility
Designed for manual chain block chain storage. Check the chain length, chain weight, and available clearance before use.
Frequently Asked Questions
Is CB-C13 for electric hoists or manual chain blocks
CB-C13 is described as a manual chain block chain bag, so it is intended for manual chain block chain storage rather than the rectangular electric-hoist CB series.
How much load can the bag carry
The specification lists a 20 kg load capacity for the container and a WLL 750 kg galvanized snap hook.
Why are there drain holes in the bottom
The drain holes help water escape so chain is less likely to sit in pooled moisture inside the bag.
