- Anchor and organise sub-ducts or multiple duct systems
- Eliminate duct-edge abrasion to cables
- Expandable gasket allows for expansion and contraction of cables or sub-ducts without leakage
- Excellent for supporting cables at the top of risers
- Effective long-term watertight and airtight seals
