The steel on this sign is very heavy duty. The sign weighs 8 lbs. The two-sided, removable sign is made of a hard foam.
It slides in either side. The size of the where the sign goes is 8 1/2 in. The size of the entire sign is 2 ft. The back of the sign has 4 steel pegs. With good measurements it would be easy to install.
Sorry about the pics of the back of the sign. My camera has trouble with that much contrast.
