Williams Comfort Products FJ-20 Flange Jacks Pair

Product Description

The WILLIAMS COMFORT PRODUCTS FJ-20 is a pair of flange jacks designed to support and level floor-mounted heating units during installation. Flange jacks provide a stable base by allowing the technician to adjust the unit's height and alignment before final anchoring. Weighing 13.581 pounds for the pair, these jacks are built for use in residential and light commercial heating applications. HVAC technicians and heating contractors typically install this hardware as part of a floor furnace or wall furnace rough-in procedure.

Flange jacks like the FJ-20 are used during the installation of floor-mounted or recessed heating appliances where proper leveling and flange seating are required before the unit is secured to the subfloor or framing. This pair is sold as a single set and is appropriate for new construction and replacement installations where the original jacks are worn or missing.
