This common, simple hook is metal with a brass-colored finish. It is the type that we see on the plain stick-style hall trees found in offices, schools, and homes. The hook has a thin back plate, measuring only 1/2 inch wide and 2 3/4 inches long. The two screw holes are vertically 1 3/4 inches apart. The hook protrudes approximately 4 inches from the surface. The total length from the base to the top of the upper arm is,6 inches.
