Products / SPD Spindle Commercial Venting Skylight

Curb-mounted venting acrylic or polycarbonate dome or pyramid skylight for larger openings, opened by a heavy-duty screw spindle with a control rod (SPD) or electric wall switch (SPD-E). Smaller sizes use a PVC internal frame (AC VCM SPD) and larger sizes a thermally broken aluminum internal frame (AC ATCM SPD), with a one-piece base frame sealed to a site-built curb with pre-installed foam tape. It is for flat or sloped roofs (0:12 minimum pitch), and the flashed curb width is limited to 1.75 in. No insect screen is included.
