Slim Design Toolboxes

Skinny boxes for pickup trucks, trailers, flatbeds, and semi tractors

We provide many different styles of toolboxes. One of our favorite styles is our skinny or slim style toolboxes. Built for everyday use for pickup truck beds, trailers, flatbeds, and semi's, our heavy duty toolboxes come with a variety of features and finishes. You can choose from our colorful collection of boxes to fit any slim design you require, or you can have us custom build a toolbox or storage box that fits any dimension you need. If you are looking for a specific color, we can probably match that too. Our toolboxes come in diamond plate, aluminum, steel, powder coated and more. So if you're in the market for a slim toolbox, or you need a more skinny style box for a certain application, we can provide it for you.
