Who it fits

Key specs for this box

Lock Type: Key-lockable lid

The lid secures with a physical key rather than a digital code or remote. This means you do not need to rely on batteries or electronics for security. It offers a reliable way to prevent unauthorized access to your gear. You should verify that the key mechanism is durable, as this is the primary defense against theft for items stored inside the case.

Waterproof: Moisture seal keeps contents dry

The unit includes a moisture seal to protect your cargo from rain and humidity. This does not mean the box is fully submersible or hermetically sealed, but it helps keep items dry in typical weather conditions. If you store electronics or paper documents, this seal provides a necessary layer of protection against the elements common in outdoor truck bed storage.

Installation: No special tools required

You can install this storage box using basic tools likely already in your garage. The design allows for a straightforward setup without needing professional help or complex hardware. This saves you time and effort compared to units that require drilling or specialized mounting kits. You can likely complete the installation quickly after unpacking the product from the box.

Compatible Truck: 1999 - 2016 Ford F-250/350 Super Duty

This box is engineered specifically for the wheel well dimensions of Ford Super Duty trucks from these model years. It will not fit other makes or different model years. You must confirm your truck falls within this range before purchasing. This precise fit ensures the unit sits correctly over the wheel well without interfering with the tailgate or bed cover operation.

Design and build details

The listing describes the SwingCase as a black storage unit made from lightweight, high-impact material. This construction choice suggests durability against daily wear while keeping the overall weight manageable. The box weighs 16 pounds, which allows for easier handling during installation or removal if needed. Its dimensions are 34 inches in height, 16 inches in length, and 8.5 inches in width. These measurements indicate a compact footprint that fits snugly over the wheel well without obstructing bed space.

According to the listing, the unit swings out nearly 180 degrees toward the tailgate. This mechanism provides direct access to the interior without requiring you to climb into the bed. The lid locks with a physical key, offering a straightforward security method that does not depend on batteries or electronic components. Inside, you will find an organizational tray to help keep smaller items separated. A moisture seal is included to protect contents from rain and road spray.

The design maintains a three-inch clearance from the truck bed. This specific gap ensures compatibility with virtually all tonneau cover types, including soft, hard, folding, and rolling styles. However, the listing notes it will not work with Undercover Flex Series Covers. The mounting location is fixed over the wheel well, which custom-fits the unit to your specific truck model. This setup prioritizes secure, weather-protected storage while preserving full access to the rest of your cargo area.
