The ultimate in custom fittings! Also known as joist panning, it is used to seal the underside of the joist space. This space is used as a run of duct, usually to channel air back through the return air system. The 16 in. width is equal to the distance of joist spacing, therefore enabling the panning to be nailed or screwed directly into the wood. Galvanized Panning 16 In.
