A heavy-duty concealed automatic door bottom seal engineered for high-performance commercial applications. Featuring Elaro’s Triple Barrier premium silicone gasket technology, it provides exceptional protection against sound transmission, air infiltration, dust, drafts and environmental leakage. Designed specifically for North American conditions, the premium silicone gasket maintains flexibility and compression recovery where conventional rubber and EPDM seals can harden, crack or lose effectiveness over time. The concealed design integrates seamlessly into the door bottom, while adjustable sealing control ensures consistent and reliable performance year after year.
