Review on Woodpeckers Pack of 50 Keyhole Hangers and Single Hole Hanging Plates by Shantel Griffin

The size of the screw I use fits well but when it slides down it pushes a easy twist out hanging channel. Instead of hanging brackets which I'm used to, the channel, after you've started hanging your item by sliding the screw into the channel, should further shape the screw head so what you're hanging doesn't fall out easily . This hanging bracket allows a fully installed propeller to pop out of the duct. This is not good. Maybe they need to explain the correct keyhole hanger design to their Chinese manufacturers.
