Roof curb
Adapter curb
Presentation
J. Journault's Adapter Curb provides roof integrity where roof top HVAC equipment size cannot be determined before the roof is installed. Base curb can be sized according to acceptable equipment brands and capacity ranges desired. No additional flashing is required during installation of the adapter frame. The Adapter Frame perfectly matches the selected roof top equipment without any field modification and is ideal for use in retrofit applications. Gas lines and conduit may be run through the Adapter Frame by using liquidtight fittings.

Description
Standard construction includes choice of base curb style RT-1, 2, 3, 4 or 5. Heavy gauge galvanized steel, fully welded and mitered corners, internal reinforcing for structural integrity, pressure treated wood nailers, fully insulated with rigid insulation.
