Eaton TWB6029 Thru-Wall Barrier Sealing Block - UL Cert

Part Number: TWB6029
Manufacturer
Eaton
Part number
TWB6029

Quick Summary

TWB6029 is a thru-wall barrier sealing block that provides reliable two-opening protection for conduit penetrations in industrial enclosures. In many installations, achieving a durable seal around wall penetrations under tight space constraints is a persistent challenge. UL certifications for US and Canada, plus ordinary/non-hazardous location classification, support safe, compliant usage across general industrial environments. This combination helps simplify procurement and commissioning, while improving seal integrity and ease of installation in wiring and connectivity projects.

Material
Elastomeric
Elastomeric sealing material provides strong abrasion resistance and sustained gasket performance, reducing seal failures and maintenance costs over time. Feature → Business Impact → Application: Reduced leakage paths and longer service life translate to lower total cost of ownership in cable and conduit penetrations within control panels and wall glands, enabling more reliable plant operations. Application: Use in general manufacturing or commercial facilities where durable, reusable seals are required. The 7.25 in length, 13.38 in height, and 6 in width accommodate typical enclosure profiles, enabling straightforward integration with existing frames and mounting patterns. Feature → Business Impact → Application: Elastomeric seals deliver consistent compression across openings, improving installation speed and reducing rework in tight-wall installations. Application: Ideal for retrofit projects where existing penetrations must be sealed quickly without panel removal. Feature → Business Impact → Application: With 2 openings and 6 frame spaces, engineers can plan dual-feed penetrations and maintain organized, scalable conduit routing. Application: Dual-cable or dual-conduit entries in control cabinets and wall barriers. Feature → Business Impact → Application: Ordinary/Non-Hazardous Location classification simplifies compliance planning and procurement for standard factory and commercial spaces. Application: Everyday industrial environments that require reliable, code-compliant sealing solutions. Certification → Compliance Assurance → Application: UL US/Canada certifications provide confidence during audits and approvals. Application: Multi-region deployments, procurement standardization. Installation Resources → Time Savings → Application: Access to installation sheets and datasheets accelerates field setup and reduces commissioning time. Application: Quick-start guidance for on-site technicians.
