Trulite Glass & Aluminum Solutions' MS300 XT Ultra-Thermal Hi-Performance Entrance Door was designed using a polyamide thermal strut for high-thermal efficiency and is engineered to provide problem-free installation. The door may be equipped with a wide range of hardware, including exit devices. The 2-3/8" thick medium stile (heavy commercial traffic) is assembled with a shear block and tie rod combination. Doors are dry glazed with 1" glazing infill. The door can be easily integrated into Trulite's thermally broken storefront systems.
