UWS 100 Gallon Transfer Tank Tool Box Combo Matte Black Steel Tank Aluminum Box Model ST-100-COMBO-MB

At Elite Truck, we recommend the UWS ST-100-COMBO-MB Tank Tool Box Combo to customers looking for value. With the toolbox built on the tank, it's 2 in 1. UWS may be the most recognized brand in truck tool boxes, but they also make great tanks. UWS put their two most popular products together, creating the tank and toolbox combinations. In addition, we believe the ST-100-COMBO-MB UWS tank & box combo is well made and incredibly versatile. 

You can use the UWS ST-100-COMBO-MB Tank & Box combo in many applications. However, we recommend measuring where you want to install this toolbox and tank combination and comparing it against the Elite Truck dimension drawings because it's a universal item. 

There are some tough jobs out there waiting for you, and part of mastering each and every task is properly equipping your truck. Succeed in any undertaking with a UWS steel transfer tank. UWS transfer tanks transform your pickup truck into the workhorse it was meant to be. Our steel transfer tanks feature a heavy-duty construction, professional-grade functionality and 100% safety testing.

UWS transfer tanks are built and tested for transporting non-flammable liquids, including diesel, to on-site vehicles and machinery. Whether you're headed out to the field or driving to the construction site, a transfer tank provides a dependable way to transport liquids. They can be used for diesel fuel, chemicals, solutions or even water for cleaning, farming and more.

This UWS combo steel transfer tank features a unique construction that sets it apart from other steel transfer tanks. Built into the L-shaped tank is a UWS utility chest tool box. However, rather than steel, the tool box is constructed from aluminum, making the combo transfer tank lighter than full-steel models. This helps keep unnecessary weight off your truck to promote longer life and better gas mileage.

The aluminum tool box of this combo transfer tank offers convenient storage and reliable security for your tools and equipment. It is constructed from .080" mill-finished aluminum and features our patented RigidCore™ technology for a high-strength lid. The lid is comprised of two aluminum plates filled with a solid foam, making it extremely strong and rigid. The lid also has a MicroSeal™ gasket to further protect your items, and it self-opens to 90 degrees for convenient, one-handed operation.

The transfer tank tool box is also equipped with stainless steel locking handles and a connection rod for operation from either side of the truck. The rod is enclosed by an aluminum guard that protects the locks from jamming and increases pry resistance.

This 100-gallon transfer tank is constructed from 14-gauge, high-strength steel to ensure maximum structural integrity and durability. The steel is covered in a matte black powder coat finish for dependable corrosion resistance. It is also available in white powder coat, giving you the option to select whichever color best matches your truck. This steel transfer tank is also constructed with 1/8" thick tabs for secure mounting in your truck bed (mounting hardware not included). It also has welded lifting hooks on the back for easier relocation in and out of the truck bed (remove all liquid contents prior to tank relocation).

UWS steel transfer tanks are built to be highly functional and reliable to help you conquer any job. Each tank is fitted with a commercial-grade, vented cap on top for easy filling and proper ventilation. The cap is key-operated to deter tampering with the interior contents. Each steel transfer tank is also equipped with a drain plug, placed nearly flush with the bottom of the tank. This allows for easy and complete draining as needed.

For safety on the job and on the road, UWS transfer tanks are constructed with internal baffles. Baffles are partial walls on the inside of the tank that help prevent sloshing of the liquid contents. This ensures an even flow and promotes better control and safety for your truck when braking and going around corners. Each UWS steel transfer tank is also fully pressure-tested, preventing leaks and ensuring safety for you, your crew and your fellow drivers on the road.

Like all UWS tool boxes and transfer tanks, this 100-gallon steel transfer tank combo is made right here in the USA for the highest quality. We also offer a variety of other tank styles and capacities to fit the exact needs of your job and pickup truck.

NOTE: This tank is DOT-compliant for transporting Class 3 combustible fuels only, such as diesel.
