HoneywellThermostat Guard, Clear, Wi-Fi, Traditional, Tamper-Proof Key Lock, 6.5H x 7.5W x 3D Inches

I bought this for my business when I saw clients messing with my thermostat. Eventually after many incidents of it being on over the weekend and huge electric bills, I decided to install this. It was super easy to install with four simple screws. Everything came included and works beautifully. Great purchase !!!

I was having trouble keeping tampering fingers off the heating control in our Scout Hall. Fitted this cover - problem solved. Easy to fit, done in a matter of minutes, looks as though it would fit any timer/thermostat control. I like especially the fact that the front lid lifts completely off, giving unhindered access to the controls for when they need to be changed.

Bought for my dad's heating clock to stop him turning it off. Very good

works to prevent tampering but makes the thermostat less sensitive

Used these in our scout hall, no more tampering with the thermostat! Good for the price and they both use the same key.

I got this to cover my grans thermostat as she has dementia and kept turning the thermostat down to 0 ( forgetting what it was for ) now it’s covered she can’t touch it

This is a useful item if you need to keep a thermostat under lock and key. The only let down is that there are no pre-made holes for cable entry if you need to install a surface run cable into the enclosure. Your only option is to drill your own hole into it and this is always risky with these types of brittle plastic enclosures as they are prone to cracking, then it's game over..

Good size which will house most room controls. Very sturdy and we have had no problems with false readings as reported by other buyers. Hard to find item which we recommend fully. Would buy again.
