In The Ditch Workman Series Toolbox
The Workman Series Underbody Toolbox from In the Ditch is a reliable way to store your gear. Set off by a mirror polish finish, the 14-ga. stainless steel door panel gives it a showroom appearance while also being very tough. Plus, the latches and hinges are both made of stainless steel ensuring durability at every point. To protect against corrosion, there is a drip edge and gasket to protect against moisture. Choose your preferred size from the drop-down menu.

Cost-Effective Solution
Like a lunch box and hard hat, the Workman Series is ready to go to work everyday. Don’t be fooled by the name though. This toolbox is just as effective as similarly-sized toolboxes but at a lower, more budget-friendly price point.
Heavy-Duty Construction
The 0.90 aluminum walls and the 14-ga. stainless steel door means this toolbox will be around for a long time. Rest assured, you won’t have to worry about corrosion compromising the strength and integrity of the box, causing you to replace it before its time. The durable steel hinges will also hold up to repeated door swings.
Professional Appearance
Stand out from the competition with the mirror finish on the stainless steel doors. You've worked hard to build a professional image. Keep it going with highly polished curb appeal.
Weatherproof Design
You’ve invested in quality equipment and tools. Now protect them from the elements with this weathertight box. The integrated drip edge and automotive-style gasket prevents road spray, rain and snow from entering the cavity and causing premature wear and corrosion to your gear.
Secure Storage
Make sure your tools stay put with stainless steel latches and keyed locks. Unlike plastic locks, the 3/16" custom latches are tamper-resistant and provide more secure storage for your expensive tools.
Versatile Sizing
Take advantage of the bonus space under your flat bed or trailer deck. Choose from several different lengths to fit within your wheelbase. The 48", 60" and 70" boxes come with dual locking latches, while the 36" size features a single latch.
Easy Installation
Cut your installation time in half with In The Ditch’s Quick Mounts. Just bolt the steel brackets to the frame rail and hang the toolbox in the frame. No more jacking up the box to install. Four sizes are available to allow for the perfect mounting height.
Flexible & Functional
Your tools of the trade will likely vary from the next guy. That’s why these Workman toolboxes are customizable with shelving, dividers and optional add-ons, like fender storage and box-top organizers.
Please note Workman Series toolboxes do not come with pre-drilled holes, giving you the flexibility to mount them where you want them.
