Dee Zee Truck Bed Side Rail Tool Box

Dee Zee Truck Bed Side Rail Tool Boxes: Smart Storage Along Your Rails

When every inch of truck bed real estate matters, Dee Zee has spent decades engineering a solution that lives on your rails rather than in your bed. Their lineup of truck bed side rail tool boxes is purpose-built to mount along the side rails of your pickup, keeping gear secured and accessible without sacrificing the hauling space you depend on. Whether you're a tradesperson running tools to the job site or a weekend warrior loading up for an off-road adventure, Dee Zee's side rail boxes deliver an organized, weatherproof home for your equipment right where you need it.

A Heritage of American-Made Craftsmanship

Dee Zee is a central Iowa-based manufacturer that has been building truck accessories since 1977 and serves as an OEM supplier for some of the biggest names in the automotive industry — with most products made and packaged in Des Moines using parts sourced predominantly from American suppliers. That manufacturing pedigree translates directly into the fit, finish, and durability you'll find across their side rail tool box range.

Tiered Series for Every Truck Owner

Dee Zee offers a clearly tiered lineup: Red Label for dependable everyday use, Blue Label for true commercial-grade abuse, and the Hardware Series for steel strength at a value price — making it easy to match performance and budget without compromise. Side rail-mount configurations are available across these series, giving you options whether you need a polished aluminum look or a tough powder-coated steel finish.

For the most security-focused buyers, Dee Zee offers their padlock-series side mount boxes. These boxes are built with heavy-duty Brite-Tread aluminum that is 20% thicker than standard side mount boxes and equipped with a recessed padlock shackle that's impossible to reach with bolt cutters — without question, the most secure tool boxes in the Dee Zee lineup. The Hardware Series, on the other hand, uses heavy-duty 20-gauge steel with a textured black NRT (No Rust Technology) powder-coat finish for buyers who prioritize steel construction at an approachable price point.

Features That Work as Hard as You Do

Dee Zee side rail tool boxes are loaded with thoughtfully engineered details. Each box features reinforced lids, gas shocks, and full weather seals to keep tools dry, secure, and protected, backed by industry-leading limited-lifetime warranties on aluminum models. From self-adjusting strikers and locking paddle handles to low-profile options that preserve rear visibility, Dee Zee boxes deliver smart security and everyday usability while maintaining a clean, professional truck appearance.

The Topsider-style side rail boxes take a particularly clever approach to storage. Dee Zee designed the Topsider to take advantage of otherwise wasted space, providing plenty of storage for tools and supplies in a secure box on top of the truck's rails — allowing full use of the truck bed for hauling cargo. A C-Channel leak-proof design incorporates a one-piece neoprene rubber bulb seal to defend against the elements, while drop-down doors provide quick access from the side of your truck.

Easy Installation, No Drilling Required

Installation is fast and easy like most of Dee Zee's boxes, using simple J-hooks to fasten the box to your truck's bed rails with no drilling required. Side rail boxes work great by themselves or paired up with a Dee Zee crossover tool box for a complete, modular truck storage system. Almost all Dee Zee products are backed with a limited-lifetime warranty , giving you long-term confidence in every box you buy.
