## Questions & Answers

**Q: Does the thermostat need to be removed from the wall in order to install this guard?**
A: The cover is open in the back so the thermostat does not need to be removed from the wall. The cover is mounted to the wall with 4 screws.

**Q: I need to order like 12 of these boxes all keyed alike. What part number do I use? It said it has an inner shelf I don't see it. What size is it?**
A: The Honeywell website carries these at $18.99 and has an option to "click here to contact them to have all boxes keyed alike". It allows you to send an email to request a matched set of keys.

**Q: I have a Versaguard  cover on another thermostat (TG511A 1000) Will the key on this cover fit that cover or that key fit this cover.?**
A: I think the key will fit a different model of cover. The locking mechanism is the same across all four the the covers I bought.

**Q: Will this fit an older circular thermostat?**
A: Yes your older circular thermostat should have no problem fitting in the unit. ~Joey

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good and strong solution
*by F***A on 12 December 2023*

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 !!!

### ⭐⭐⭐⭐⭐ Easy to fit
*by D***D on 30 April 2017*

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.

### ⭐⭐⭐⭐⭐ Cover
*by C***Y on 13 August 2023*

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