Honeywell thp2400a1050u Thermostat Coverplate Assembly

Product Description

The HONEYWELL thp2400a1050u is a cover plate assembly designed to give HVAC technicians and installers a clean, finished look when replacing or repositioning thermostats on residential walls. The kit covers scuff marks, paint outlines, or holes left behind by older thermostat footprints, and it also supports mounting directly to a standard 2-inch by 4-inch electrical junction box. The assembly ships in Arctic White and includes both a square plate measuring 6.12 inches by 6.12 inches and a rectangular plate measuring 5.5 inches by 6.9 inches, along with a bracket and all necessary mounting hardware.

This accessory is suited for residential thermostat replacement projects where the wall surface behind the old stat is damaged or mismatched. It simplifies changeouts on new-construction and retrofit jobs alike, eliminating the need for patching and repainting. The two-screw mounting design keeps installation straightforward and secure. The included j-box bracket expands the mounting options when a flush-wall installation is not feasible or when the wiring stub-out is housed in an existing electrical box.
