Rantings of an old man: Smoke detector brackets

[Jeff-Groves]

The easy way to prevent the sticky tape smoke alarms from coming loose.

Get the round cover plates from a junction box and use screws to attach it.
Then mount the box with sticky tape to it. It will hold nearly forever!

To remove the alarm plate?
A thin wire like a piano wire will cut through the sticky tape. Then scrape with a razor knife if needed.

Now those of us in the Construction trades use a self made Hot knife to remove that tape.
