Eaton CB9 Clampback/Spacer - EMT/Rigid, NEC/CEC
Part Number: CB9
Quick Summary
Eaton CB9 clampback/spacer is a mounting accessory designed to secure EMT and rigid conduits, delivering reliable spacer support for industrial electrical installations. In tight panels and crowded cable trays, installation can stall due to misalignment and limited space; the CB9 minimizes field adjustments and rework by providing a sturdy, single-part solution. It is designed to meet NEC/CEC standards and is UL-certified for EMT installations, making it suitable for Ordinary/Non-Hazardous Locations. This clampback/spacer also reduces parts diversity, streamlines procurement, and supports consistent conduit spacing across runs, helping contractors and OEMs achieve faster commissioning and predictable performance in harsh manufacturing environments. Incorporating CB9 into projects translates into improved installation efficiency and lower lifecycle costs.
