3M Claw 3PHM-8CLUB-CS Hangers, Assorted, Grey

I have used these for drywall that struggles even with drywall plugs. I have hung several heavy mirrors and pictures and not had a single accident. The only issue is that I struggle to push them in and have to resort to light taps of a hammer. The hangers are also easy to remove with a screwdriver allowing them to be used again, and only small holes are left on the wall. I have also noted that 3M has been responding to people saying that you can use, for example, two 30lb hangers to mount a 60lb item. This is incorrect and says as much on their own packaging! You must use the hanger that is designed for the weight so a 60lb item will require 60lb hangers.
