The single Tunnel Inlet Door comes fully assembled and an ultra-lightweight, rigid laminate foam panel with aluminum channels on all edges makes for easy installation. Molded runners on the “P” seal allow for easy alignment and quick installation.
With an insulation value of R-8, the Tunnel Inlet Door provides excellent energy savings compared to conventional curtain inlets. The lightweight rigid laminate foam panel construction includes a profiled rubber “P” seal for an airtight fit.
All brackets are galvanized for durability and long-life. Over time, cords can stretch requiring tension readjustment. Cumberland’s Ratchet-style Cord Adjuster makes ensuring a reliable door seal a simple task.
