Frigibar's 500U “Salty Dog” Watertight Utility Deck Box is designed like a briefcase with flush fitting sides and domed top, these handsome boxes incorporate full length piano hinges for strength and an automatic lid support cord for convenience.

The recessed hasp on the marine dock boxes allow a padlock to hang flush while forming a handle for opening. Internal drain holes make these boxes self-bailing when storing wet dunnage, while incorporating louvered air vents for minimizing mildew formation.

A deck contour can be profiled into the box skirt for leveling, imparting a custom look which make these boxes so desirable.

Please be aware that Frigibar may need to construct your unit!  If this is the case there may be a 4-6 week build time for this custom refrigerator to be built and delivered to you!  Contact us with questions at 877-230-7353 or [email protected]
