This dust resistant enclosure is primarily designed for a larger clock terminal that the card drops in the top like an Amano MJR or CP3000. It is manufactured from 18 gauge steel and then powder coated with a durable outdoor powder coat. The door comes with "spring hinges", a pad-lockable hasp, and a gasket at the opening. The overall dimensions of this enclosure are 24" high x 11" wide x 9 1/2" deep. Even though this enclosure is designed to keep the dust out, it is NOT weather resistant.
