BISupply A/C Thermostat Lock Box with Key L 1pk - Plastic Locking Wall Thermostat Cover - Lockable Heat and Air Condition Control Panel Cover

Was able to hide temperature control settings. Size was perfect. Works great. Easy to install. Value for the money spent.

Mi hija de 3 años es muy traviesa y siempre movia el aire sin darnos cuenta. Y compre esto y problema solucionado 😅

This product is well made. I had to use the 2nd mounting plate for wall mount to make the cover work with my thermostat. That said, the fit was still a bit tight as seen in the attached photo where the temperature setting levers interfered with the cover box and does not allow for free movement for temperature adjustment. The problem with the dimensions that the manufacturer listed as the 'inside dimension' is that it is the inside dimension of the cover but it does NOT take into account of the key lock opening protrusion into this space on the backing plate where the thermostat has to fit into!!! This key lock opening is in the back plate so it technically is not inside the cover but makes a difference. As can be seen in the enclosed photo, the thermostat is installed as low as possible and is forced against this key lock opening and yet, the temperature control levers on top still comes into contact with the cover box!!! Be sure to measure your thermostat height INCLUDING the temperature set levers and add ONE INCH just to be sure it will fit!! I give it a TWO STAR for incorrectly stating the inside dimension as it should have taken into account of the protrusion of the lock opening that is on the back plate!!!

We purchased this guard to keep our grandchildren from being able to turn on the gas fireplace in the reckroom without our permission. Just incase. Very happy that we can lock the switch for safety.

Sent it back because it was too big.

I really like this product because, my children can’t change the temperature settings over and over all day long. And due to this product. It has saved me money.

It wasn't durable at all

Very easy to install and exactly what I needed to keep my 2 year old twins from changing the temperature!!!! This will be a life saver!!! It only comes with one key but that's okay since it's on with the rest of my keys.
