*Pending pickup* Smoke detectors, battery powered (Canton)

Free to pick up in Canton, Mass (minutes from Cobbs's Corner): Seven battery powered smoke detectors, mfg'd in 2017.
Three are missing the mounting bracket.
Maybe you can use them.
Be sure to click "more ads by this user" below, as I am clearing out my storage shed, and things gotta go! I travel to Clinton, Norton, and sometimes Blackstone.
Can arrange a meet or delivery.
May ask for gas $$ if not on my route.
