Draft Seal Kit For Non-Metallic Boxes, 1 Gang, Foam

Southwire DraftSeal Box Accessories are designed to help seal electrical and communication wall box openings in exterior walls to support energy-efficient building envelope performance. Engineered to work with most standard nonmetallic boxes, including shallow and deep variations, these accessories help reduce air leakage, drafts, vapor intrusion, and sound transmission through walls. The system features a green front flange that remains visible after drywall installation for easy identification, along with foam sealing components that attach to the box to help create a reliable seal. DraftSeal Box Accessories provide a fast, clean alternative to caulking and sealants and support compliance with IECC and LEED envelope sealing requirements.
