Products / SR1800 6 in. Riser and 3.5 in. Curb Mount

Two mounting components for Solar Royal's SR1800 Series solar attic fan, sold as fan accessories. The 6 in. riser (SR-R603) fits between the fan's aluminum base and its hood to add six inches of clearance, which Solar Royal describes for tile roofs, sod or grass roofs, snowy areas, metal roofs and other commercial applications. The 3.5 in. curb mount (SR-CB635) is a solid aluminum base with a 3.5 in. lip for setting the fan on a curb. Solar Royal's 2025 component specification sheet names both parts and its site links a riser installation video guide.
