Eaton TWB70111 Thru-Wall Barrier Sealing Device - UL Canada Certification
Part Number: TWB70111
Quick Summary
TWB70111 sealing block assembly by Eaton Crouse-Hinds provides thru-wall barrier sealing for cables and conduits in equipment enclosures. Design engineers often struggle to preserve enclosure integrity while routing penetrations, risking ingress paths and costly field rework. It is rated for ordinary/non-hazardous locations and supported by Canadian certifications, with UL installation sheets and a dedicated specification sheet. Elastomeric construction supports a 4.250-4.500 inch opening in a single block, designed for seven frame spaces, enabling fast, repeatable installations. This combination lowers lifecycle costs and helps ensure regulatory compliance across industrial facilities.
