Imperial Galvanized Steel Joist Panning

Effectively create return air ducts between joists or studs with this Imperial Joist Panning Lining. The 16-1/12″ x 30″ joist lining seals the underside of floor joist space, creating a duct run to channel air back through the air return system. This allows you to nail or screw the lining directly into the wood, creating a run of rectangular duct. The panning lining is constructed from 30-gauge galvanized steel for rust resistance and lasting durability. It can be cut to size to fit a variety of applications, and is easy to install with sheet metal screws for a secure fit (screws sold separately). This joist panning lining is suitable for use in most heating, venting and air conditioning applications.Seals the underside of floor joist space to create a return air duct between joists,Constructed from 30-gauge galvanized steel for durability and rust resistance,Can be cut to size to fit a variety of applications,Can be nailed or screwed directly into wood,Galvanized steel construction
