Daylighting

UL Listed Daylighting Smoke Vents

R&S Daylighting Smoke Vents carry a UL 793 rating. The lids automatically open when the fusible link activates at a preset temperature. Our complete line of vents meet local fire codes and have the added benefit of allowing natural daylight to enter the building. The curb base may be aluminum or galvanized steel. The metal building option includes a curb base that fits any standing seam, panel rib or insulated metal panel roof. Curb mount models are also available which can be built to fit most curb sizes. All R&S Smoke Vents have both inside and outside release handles with automatic braces that keep the lids open. These products may include McCabe links which open the lids from the ground level (controls by others). OSHA compliant safety screen is available to prevent a fall accident.
