Series 900 Horizontal Slider

The horizontal sliding windows are smooth operating with right or left sash operation options available. This assembly can be glazed with 3/4- or 1-hour Underwriter’s Laboratory rated protection. The window is designed and tested to be self-closing in the advent of heat rise from nearby combustion or optionally an alarm signal. Ideal for inclusion in construction when required by NFPA 80 and building code requirements for protective openings in rated walls.
