Products / Curb Adapters and Extensions (CA-1, CA-2, CE-1)

Unitized galvanized steel adapters that sit on an existing roof curb so new equipment or a skylight of a different footprint can be installed without replacing the curb: CA-1 for units larger than the existing curb, CA-2 for smaller units and CE-1 extensions for units of the same size. They are made of 18 gauge galvanized steel with continuous welded corner seams; the CA-1 product page lists 1 in. of 3 lb. density fiberglass insulation, while the adapter submittal form lists 1-1/2 in.
