Adaptor Curbs

Product Description

Custom fabricated adaptor curbs are designed to retro-fit your current base curb when new air handling equipment is installed. Adaptor curbs eliminate costly reconstruction without disturbing the existing roof or ductwork. They also save engineering and construction time and reduce customer inconvenience.

Conn-Fab offers two styles of adaptors for your convenience. The traditional style, with an open bottom, provides for duct transition within the adaptor. The plenum style, provided with an insulated floor and partition to separate airstreams, eliminates the need for additional duct work. Standard construction for either style consists of 18 to 14 gauge prime galvanized steel, continuously welded seams and corners, and internal reinforcement as required. All adaptors are fully insulated with 1 1/2″, 3# density standard insulation or plenum board designed for airstream use.
