This listing is for two (2) Cargo enclosed trailer door hinges. These are made from heavy gauge steel. Pre formed holed to fit carriage bolts. PLEASE NOTE: Mounting hardware such as bolts, nuts, washers or screws are NOT INCLUDED! Also note that zinc plating is plated over the steel. This process can appear as a swirl or scuff look. The plating is done in a liquid bath and when done light scratch appearance can be seen from the withdrawing from the plating bath. This does not effect the performance of the plating and is a common effect of submersion plating. Your hinges will arrive with this look.
