Black & Polished Z-Door Zero Clearance Bronze Glass Bifold Tracked Door For Lennox & Superior BR-42, BC-42, BRF-42 and BCF-42 Models. Thermo-Rite's stock Z-Doors are made as inside fits. We use Air Studs™ or an Air Draft Bar™ to elevate the frame so that it maintains the cooling air intakes located inside the firebox. In most applications, we allow an air space between the outside of the enclosure and the firebox opening. The Z-Door is a sleek, full-framed, tarnish free anodized aluminum enclosure.
