Maverick Crossbox (Lt. Truck)

The Maverick Crossbox is our aluminum crossover truck bed toolbox, built for the light-truck crowd who want clean looks and serious durability.

Welded from marine-grade 5052 aluminum, the Maverick Crossbox mounts across the bed rails of any pickup, giving you secure, weather-resistant storage without giving up bed space below. The low-profile design keeps your truck looking sharp while holding up to daily use, job-site grit, and whatever the seasons throw at it. Like everything we build, it's made to order and built to last the life of your truck.

Type: Crossover / truck bed toolbox

Topside Boxes

Topside boxes mount along the top rails of a flatbed or service body, putting tools and gear at waist height for easy reach without bending into the deck.

Wickum Weld builds aluminum topside boxes sized to run the length of your bed or in shorter sections, depending on how you load and what you carry. Welded from marine-grade aluminum and built to order, they give crews fast access to frequently used tools while keeping the deck clear for cargo.

Built For: Flatbeds, service bodies, commercial rigs
Type: Top-rail mounted storage
Material: Marine-grade aluminum

Underbody Boxes

Underbody boxes mount beneath the deck, between the frame and the wheels, making use of space that would otherwise go to waste. They're ideal for heavier tools and gear you want secured and out of the way.
 
Wickum Weld manufactures aluminum underbody toolboxes built to your truck's frame dimensions, welded for strength and weather resistance. Made to order and built to take the abrasion and road spray that comes with mounting low on a working truck.

Step Boxes

Step boxes do double duty: secure storage plus a sturdy step up onto the deck or into the cab. For crews climbing on and off the truck all day, that combination saves time and wear.

Wickum Weld builds aluminum step boxes welded to handle both the load inside and the weight on top, day in and day out. Stock sizes are on hand and ready to ship while unique sizes are Built to order.

Built For: Flatbeds, service bodies, crew trucks
Type: Combination step / storage box
Material: Marine-grade aluminum

In-Frame Boxes

In-frame boxes fit within the truck's frame rails, tucking storage into the chassis for a clean, low-profile setup that keeps the deck and sides clear.

Wickum Weld manufactures in-frame toolboxes built to your truck's frame specifications, welded from marine-grade aluminum for a tight, durable fit. Made to order for operators who want maximum storage with minimal intrusion on usable deck space.

Built For: Flatbeds, service bodies, commercial trucks
Type: Frame-rail integrated storage
Material: Marine-grade aluminum

Custom Toolbox Options

No two trucks carry the same gear the same way, so we don't build every box the same. Every Wickum Weld toolbox is made to order, and we'll configure yours around how you work:

Custom Dimensions — built to your bed, deck, or frame measurements
 
Coordinated Layouts — topside, underbody, step, and in-frame boxes designed to work together
 
Locking & Latching — secure closures sized to the box and the job
 
Fleet-Spec Builds — matched configurations so every truck in your fleet is identical Material Grade — marine-grade 5052 or aircraft-grade 6061 aluminum, chosen for the application

If you have a layout in mind, we'll work with you from design through delivery — every weld done in-house at our manufacturing facility.
