Fiberglass Dock Boxes

Dock Boxes provide a stylish and convenient place to store and organize everyday items that you use on your boat or dock. Fishing gear, ropes, life jackets, and water sports gear can now be tucked away in your dock box, keeping your garage less cluttered and saving you from carrying the same items back and forth to your dock. Dock boxes are also a perfect addition to backyard decks, pool decks, and patios. They are great for storing your yard tools, pool toys, and accessories. Whether you need a triangular box with electrical inset or a rectangular box with fishing rod holders under the lid, we have you covered. In addition, we offer space saver boxes, low-profile boxes, patio storage boxes, and much more. If you're looking for reliable and stylish storage for your dock or marina, then look no further than Dock Builders Supply! We have a large selection of dock boxes that are in stock and ready to ship!


Classic Dock Boxes are constructed from heavy duty white fiberglass with an average 3/16” wall thickness. Lids are constructed with a strong, sandwich-core design for unsurpassed strength. The smooth UV gel coated exterior provides long-lasting beauty and protection. Interior features a gel-coat finish with black webbing. Stainless steel hinges, gas shocks, and lockable latch are mounted with stainless steel lock nuts and machine screws (not riveted). All models are fitted with gas shocks to make opening the box effortless and closing more controlled. Stainless steel vents come standard on select models. Deep and low-profile models are available.


Deluxe Dock Boxes are high end, high quality, yet affordable products that feature sleek rounded edges, domed lids, and 5” stainless steel vents on both ends. They are constructed from heavier duty white fiberglass with an average thickness of 1/4”. All cut and exposed edges are gelcoated. The UV gel coated exterior provides long-lasting beauty and protection, while the interior features a white gel coat finish with black webbing. Stainless steel hinges on the lid are mounted with stainless steel lock nuts and machine screws (not riveted). Each box includes two stainless steel lockable latches. Gas shocks allow for easy opening and soft closing. Our 33” tall boxes provide enough room to store dive tanks in an upright position.


Premium Dock Boxes are constructed from heavy duty white fiberglass and feature a smooth UV gelcoat finish on both the exterior and interior, making them easier to clean and gentler on your hands when retrieving items. All models are fitted with gas shocks, stainless steel hinges, and a lockable latch.
