Add the Extreme Aluminum Diamond-Plate Trailer Tongue Locking Storage Box to the front of your A-frame trailer for an attractive, rugged storage solution! The tough diamond-plate finish goes well with any trailer setup, and the locking top provides a comfort in knowing your valuables are safe. The weatherproof construction provides dry storage, no matter the conditions. Each box contains a set of keys. Due to the variety of surfaces to which the holder may be mounted, mounting hardware is not included.
