Description
Finish your thermostat installation with a clean, professional look using the Model 2940 Vertical J-Box Adapter Wall Plate. Designed for HVAC contractors and homeowners replacing or relocating a thermostat, this adapter plate conceals drywall damage, paint outlines, screw holes, and oversized cutouts left behind by a previous thermostat — eliminating the need for patching, sanding, or touch-up paint.
The 2940 mounts over a standard vertical electrical junction box and provides a crisp, neutral backdrop for your new thermostat. A central wire pass-through slot routes low-voltage control wires cleanly to the thermostat base, while side-mounting screw holes secure the plate flush to the wall for a tight, gap-free fit. The bright white finish blends with virtually any interior wall color and pairs with most modern residential and commercial thermostats, including smart and programmable models.
Whether you’re upgrading to a slimmer thermostat footprint or swapping out a legacy unit, the Model 2940 saves installation time and delivers a finished appearance your customers will notice. Backed by a 1-year warranty.
