Eaton CB4 Clampback Spacer - 1-1/4 EMT/IMC, Stamped Steel

Conduit compatibility is a core feature: the CB4 is designed for EMT and Rigid/IMC conduit in 1-1/4 inch trade size, built from stamped steel for rugged service. This combination yields solid mechanical support and consistent spacing, translating to fewer field adjustments and faster panel wiring. In practice, installers can complete runs with greater confidence and less rework, especially in dense industrial enclosures where space is tight. The stamping process also contributes to dimensional stability even under vibration and temperature cycling. Compact dimensions and lightweight profile: with a length of 3.44 in, width 1.88 in, height 0.75 in and a weight of 0.21 lb, the CB4 minimizes added bulk while maintaining robust clamping force. The compact form helps when routing multiple conduits through limited clearance and supports clean, professional installations in lighting and emergency system layouts. Quick-hand install sequences reduce tool time and lessen fatigue on busy jobsites. Compliance-focused design: NEC/CEC standards alignment and Ordinary/Non-Hazardous area classification ensure the spacer meets common code requirements for non-hazardous locations, reducing review cycles. Canadian certification references further simplify cross-border projects, limiting the need for alternate hardware and streamlining procurement for multinational facilities. This combination helps QA teams demonstrate compliance during inspections. Installation and compatibility advantages: CB4 works with standard clampbacks and spacer assemblies in the Crouse-Hinds family, enabling straightforward integration into existing wiring methods. The stamping supports repeatable fitment across batches, reducing misfit hardware and warranty issues. For manufacturers and contractors, CB4 offers an OEM-friendly option that scales across equipment racks, panels, and racks where space is at a premium. Industry context and ROI: for panel builders, OEMs, and electrical contractors, standardizing on CB4 reduces part variety, procurement complexity, and field labor. The result is a lower total installed cost, faster project turnarounds, and predictable performance in lighting and emergency systems that demand reliable conduit support while maintaining ongoing compliance.
