Q-Mark QSF2448 48x24 Surface Mounting Frame
The Q-Mark QSF2448 is a surface mounting frame designed for commercial heating installations. It provides a secure structural border for compatible heater units in professional environments. The frame suits contractors and facility managers fitting surface-mounted equipment.
UL and CUL Listed White Frame Extends 1/8 Inch
The frame carries UL Listed and CUL Listed safety certifications for code compliance. Its white finish integrates cleanly into commercial ceilings or walls. The frame extends only 1/8 inch from the mounting surface for a low-profile fit. Surface mounting simplifies attachment to flat structural surfaces.
For Use With 54UD26 Through 54UD29 Heater Models
This frame replaces makeshift mounting solutions when installing 54UD26, 54UD27, 54UD28 or 54UD29 heaters. The upgrade is worth it when a listed, dimensionally precise frame is required by specification. It is not for installers using heaters outside that model range.

The frame carries both UL Listed and CUL Listed markings, confirming it meets the applicable North American safety requirements for commercial heating accessories.
What outside dimensions and compatible heater models should I verify before mounting the 48 by 24 inch frame?
The frame measures 48 inches high by 24 inches wide and is designed for use with heater models 54UD26, 54UD27, 54UD28 and 54UD29.

The frame mounts directly to the wall surface and extends only 1/8 inch, so installers must ensure the rough opening accommodates that minimal projection rather than leaving a larger gap.
