Roof Curb Adapter for 24 in Curb

The Dayton 6KWP5 adapts a 22 in fan base to fit a 24 in roof curb. It suits downblast fans, filtered supply fans and upblast fans. The galvanized steel construction uses 18 ga material thickness. Installers needing to bridge this specific size difference will use this adapter.

Installation Uses Supplied Fasteners

Eight 1/4-20 Tinnerman speed nuts and eight 1/4-20 x 3/4 bolts are included for the connection. Two fasteners per side secure the adapter to the curb and fan base. The overall height is 5 in with a top flange height of 2 1/2 in. Misalignment occurs when the fan base does not match the 21 1/2 in dimension.

Verify Fan Base and Curb Dimensions

Confirm the existing roof curb measures 24 in on each side before ordering. Ensure the fan base is 21 1/2 in wide to match the adapter's fan side width. The adapter functions only as an increaser for this specific size step. It does not suit curbs or fan bases of other dimensions.
