Dock Boxes Cutouts 01

Dock Boxes

Keep your dock organized and your gear secure.

Highway Products builds our Dock Boxes using 1/8"-thick, military-grade aluminum, semi-truck tough locks, a bulletproof full-length piano hinge, and a rugged powder coat finish that'll stand up to the weather. We have many sizes to choose from, or ask for a special size to fit your boat dock or storage needs. Got a special feature you need? No problem. We do this every day.

HPI Benefits

The HPI difference is in the materials we use, the attention to all details and ultimately products we produce and proudly guarantee. Our promise is to take the best care of your product while we manufacture it, and continue to care for a lifetime after you receive it.

Lifetime Warranty

All of our products come with a Lifetime Warranty against defects in manufacturing (failed welds, etc.). It also includes all locking mechanisms, hinges, gas shocks, weatherstripping and any other materials we use. Learn More

Military Grade Aluminum

Highway Products uses nothing but the best materials. Our products are hand crafted out of Military Grade aluminum. Why take it that far? The days of using nothing but the best ingredients are all but gone in this world. We refuse to sink to that level. That’s the HPI difference.

Product Features

All HPI products come standard with options and features that you would normally pay extra for. Please explore all of our standard and optional features and call us with any questions you may have!

  • Door Props
    We give you a choice of chains or gas charged door props for your dock box. The advantage of chains is the door opening is bigger, easier to get your cargo out, and chains last forever. However, a gust of wind may blow the door closed at times.
  • Mounting System
    We weld a 1/4 inch reinforced aluminum mounting bracket to the sides of our dock boxes to ensure a strong and water-tight mount.
  • T Handle Locks
    Our ergonomically designed T-Handle locks are the most secure locking mechanism on the market.
  • Tote Trays
    We put these handy aluminum trays in almost every dock box we make. They're great for small items you use down at the boat dock like suntan lotion, wax, soap, cleaning materials, bug spray, and tools. Plus, you can carry them around.
  • Watertight Seal
    We use Clean Seal™ automotive stripping around the edges of our Dock Boxes to ensure a watertight seal.
  • Welded Rope Hooks
    We've welded rope hooks directly to our Dock Boxes which adds extra contact points for securing your load.
