Box Frame Belt Buckle

Box-frame belt buckle is one style of the military friction buckles. The box-frame buckle consists of three parts (front, back and post). An adjustable captive post sits perpendicular to the belt to press it against the outer "box," which completely surround the webbing and minimize accidental adjustments should part of the belt snag on something. There is a metal tip on the opposite "tongue" end of the belt for easier insertion.
