THP2400A1080 Large Cover Plate & Electrical Box Adaptor for T-Series Thermostats, White (1)

I love haw it fits and hides all the blemishes from the electrical box. It installed in minutes and the Lyric thermostat snapped right into place.

Great fit

The ARYEIELLSOW THP2400A1080 Large Cover Plate & Electrical Box Adapter is a practical solution if you’re upgrading to T-Series thermostats and want to cover any gaps left by older models. The cover plate’s design is simple and clean in white, so it blends seamlessly with the wall. Installation is straightforward, and it effectively hides any inconsistencies around the electrical box, giving a neat, finished look. It’s a great little accessory to make thermostat upgrades look professional without extra wall patching.

The listings have to do better at explaining what thermostats these are compatible with. Meaning it’s compatible with most Honeywell thermostats that use that universal wire hub. This plate will work with thermostat model X2P.

Perfect fit

This was a great backplate for the T9. One of the backplates that I received had one of the 3 locking pieces broken off, however, it still looked like it would be usable and felt solid. I had to return the product due to the T9 thermostat not being compatible with my HVAC system.

I got this cover plate to keep the drafty air (coming from between the wall) from seeping out around my thermostat. That air was causing my thermostat to have an inaccurate reading of the overall room temperature. The cover has worked perfectly, and it looks great!! A perfect, inexpensive alternative to the name brand.

I had to replace several Nest thermostats with Amazon branded ones and found that the old thermostats were mounted to junction boxes. The OEM branded junction box adapter and cover plate were more than double the cost of this brand. If it was metal like the Nest version, it may be worth it but since it is all plastic this brand is a worthwhile alternative. I install all four with no problem. Also, the size is as wide as the Nest wall plate but also a square so it covers more area (see photo). I was a bit concerned at first if it was smaller as the wall was painted recently. Lucky, it is a tad bigger so no need to re-paint.One issue that since this uses tabs to hold the thermostat that the wiring unit can be pulled off this mount. The default installation method would have used screws to hold the wiring unit to the drywall or wall cover. However, this design is the same in the OEM junction box adapter so I can't fault this product. It would be a nice improvement if it allowed for screws though.
