I hate the keyhole slot they put on power strips. They are a pain in the butt and don't really secure the power strip, so it ends up coming loose.

Print these little brackets and screw your strips to the wall, workbench or cabinet. It holds the power strip securely in place.

I always thought it was just me that hated those things

Now if someone would only make power strips with half the sockets at 90 degrees to the other half so you could pick the appropriate one to plug in wall warts with different power prong orientations :-).

They do make them, you just need to search for them. They even have them where each socket can rotate to whatever angle you need.

i zip-tied mine to the underside of a wire shelf.. works for me.
