Surface Mounting Frame for 24-Inch HVAC Units
This Q-Mark QSF2424 mounting frame provides a surface-mount solution for compatible HVAC controls. It is designed for installers fitting 54UD-series equipment into walls or ceilings where recessed mounting is not possible. The white finish matches standard commercial interiors.
Sustained Structural Support Under Load
The frame extends 1/8 inch from the mounting surface to maintain a consistent gap around the control unit. UL and CUL listings confirm the assembly meets safety standards for continuous operation in heating and cooling cycles. Rigid construction prevents flex that could stress connected ductwork or wiring over time.
Straightforward Surface Installation
Pre-drilled holes align with the 54UD22 through 54UD25 models for direct fastening to the mounting surface. Installers must verify the 24-by-24-inch outside dimensions match the rough opening before cutting. The shallow 1/8-inch projection leaves minimal tolerance for uneven walls, so shimming may be required on irregular substrates.
