Really nice heavy duty battery box for a pair of batteries. Strong rigid plastic with matching vented lid that screws down with plastic fasteners. Also included molded in nuts to you can bold it from the bottom and fix it on a surface. Never used, but has been sitting around for a while in the garage. Internal dimensions are 21" wide, 11 1/4" deep, and 12" high. Thanks for looking! Email, or text / call.
