Locking metal buckle and capsules with thick urethane strap.
The buckle and metal capsules are made by Bat prop maker Henry Wayne.
The strap is the side trim molding from a 1988 Chevy Silverado truck, which is the source of the original belt design. In the original prop, the trim part and capsules were pulled as a single cast from a mold made based on the auto part. For this replica piece, an actual piece of original trim is used.
