This dust resistant enclosure is primarily designed for a TOP LOADING time clock. 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 20" high x 10" wide x 7 1/2" deep. Even though this enclosure is designed to keep the dust out, it is NOT weather resistant.
