This is a strong steel coat hanger that hangs on a door, so you don't need any tools to put it up.
There are six double-hooks.
The double-hooks are 3-1/4" apart.
The backplate of the hooks hangs 8-1/4" from the top of the door.
The maximum thickness door that your door can be is 1-3/4".
The steel of this hanger is 1/8" thick.
The steel is brass plated to prevent rust.
These hanging hooks are lightly used, but are in undamaged, excellent condition.
