Weather Guard Crossover Boxes

Shop Weather Guard crossover boxes, also called saddle boxes or crossover tool boxes. A crossover box spans the bed directly behind the cab and rests on both bed rails, giving you large, lockable storage you can reach from either side of the truck. Weather Guard crossover boxes are American-made, backed by a limited lifetime warranty, and available for full-size and mid-size pickups in aluminum and steel. Most orders ship within 1 business day from our strategically located warehouses across the US. Compare every style in Weather Guard tool boxes or see the full Weather Guard lineup.

Weather Guard Crossover Box Sizes

• Standard: The everyday crossover profile for full-size and mid-size trucks.
• Deep: Extends further down into the bed for more storage volume.
• Low Profile: Sits lower above the bed rails to keep more rear-window visibility.
• Extra Wide: Adds storage space for crews carrying larger tools.

Single Lid vs. Gull Wing

Single-lid boxes open with one large lid for full access to the box. Gull wing boxes have two lids that open from each side of the truck, so you can reach your tools from the driver or passenger side without walking around.

Aluminum or Steel

Weather Guard makes crossover boxes in aluminum and steel. Aluminum saves weight and payload; steel and aluminum versions are priced differently, so compare both on the product page.

Weather Guard Crossover Box FAQs

What is a crossover tool box?

A crossover tool box, also called a saddle box, mounts across the truck bed behind the cab and rests on both bed rails. It leaves most of the bed floor open beneath it for hauling.

What is the difference between single-lid and gull wing crossover boxes?

A single-lid box opens with one large lid. A gull wing box has two lids that open independently from each side of the truck, so you can reach tools from either side.

What does low profile mean on a crossover box?

A low profile crossover box sits lower above the bed rails than a standard box, which keeps more of your rear-window view open while still giving you lockable storage.

Can I mount a crossover box over a transfer tank?
