Eaton TWBS4036 Thru-Wall Barrier TWB - Marine
Part Number: TWBS4036
Quick Summary
Eaton TWBS4036 Thru-Wall Barrier sealing block assembly shields cables in marine enclosures. Maintenance of seal integrity across multiple openings in harsh, humid environments remains a frequent procurement challenge for offshore and coastal facilities. This block is UL-listed for Canadian certification and supports ordinary/non-hazardous locations, with certified conduit fittings to meet regulatory expectations. It’s built from elastomeric material and configured for three openings within a 1.750–2.000 in range, using four frame spaces for solid mounting. The marine-grade design reduces retrofit time, minimizes leaks, and lowers lifecycle costs, while compatible with standard installation practices and TWB sealing devices across Eaton’s Crouse-Hinds family.

FAQs
Begin by confirming four frame spaces are available and that three openings align with your incoming cables or conduits. Use the IF 1020 installation sheet to guide the sealing block placement, verify the 1.750–2.000 inch opening range, and ensure elastomeric material seats firmly against the housing to prevent leaks. This approach minimizes retrofit time and ensures long-term seal integrity in marine environments.
