Product Identity

The Dayton 6KWP6 is a galvanised steel roof curb adapter that reduces a 25 1/2 inch fan base to fit a 24 inch curb. It suits HVAC installers fitting downblast, filtered supply or upblast fans onto existing roof openings. The assembly stands 5 inches tall with a 2 1/2 inch top flange and is manufactured from 18 ga steel.

Fitment Guidance

This adapter is for contractors who must match a 26 inch fan base to a 24 inch curb without modifying the roof structure. Builders who need a straight-through curb or a larger reduction step should evaluate other options. The kit includes eight 1/4-20 Tinnerman speed nuts and eight 1/4-20 x 3/4 bolts, providing two fasteners per side.

Critical Specification

The adapter transitions a 25 1/2 inch fan-side width down to a 24 inch curb-side width. Confirm that both the fan base and the existing curb match these dimensions before ordering.

Questions about this item

What does the 24 in to 25 1/2 in adapter size mean for my roof fan installation?

It lets you mount a fan with a 25 1/2 in base onto an existing 24 in square roof curb, bridging the 1 1/2 in difference so the fan seats securely without modifying the curb.

How does the 18 ga galvanized steel construction affect durability and mounting?

The 18 ga galvanized steel resists corrosion on the roof and provides enough rigidity to hold the fan base; it comes with eight 1/4-20 Tinnerman speed nuts and matching bolts for a bolted connection.

Will the 5 in overall height and 2 1/2 in top flange clear my roof flashing and curb?

The adapter adds 5 in of height with a 2 1/2 in top flange, so check that your flashing and curb allow this extra stack-up before ordering.
