Who it fits

UnderCover SwingCase Key Specs Explained

Compatible Truck: 2017 - 2022 Ford F-250/350 Super Duty

This storage box is engineered specifically for Ford Super Duty trucks built between 2017 and 2022. You must verify your model year and truck class before purchasing. It will not fit other years or brands. This strict compatibility ensures the mounting hardware aligns correctly with your vehicle's wheel well. Check your owner's manual or VIN to confirm your truck falls within this production window for a proper fit.

Tonneau Compatible: Compatible, 3-inch clearance

The unit maintains a three-inch gap from the truck bed surface. This space allows it to work with soft, hard, folding, and rolling tonneau covers. You can close your cover without interference from the storage box. This clearance is critical if you already own a cover or plan to install one later. It ensures your bed cover operates smoothly without hitting the storage unit during closure.

Mounting Location: Wheel well

The box attaches directly to the driver-side wheel well area. This location keeps the storage unit low and out of the main cargo space. It preserves your bed capacity for larger items while providing secure storage for smaller tools. Mounting here also protects the box from being bumped by cargo. You gain easy access from the tailgate without moving other items in your bed.

Lock Type: Key-lockable lid

The lid includes a key-operated locking mechanism for security. You can lock your valuables inside to deter theft. This feature is essential for storing tools, electronics, or personal items. The key system adds a layer of protection beyond simple latches. Ensure you keep your keys safe, as losing them may require professional intervention to open the unit securely.

Design and Build Overview

The UnderCover SC205D is constructed as a durable storage unit for your truck bed. According to the listing, the main body is finished in black. This color choice helps it blend with most truck bed liners and existing hardware. The unit measures 34 inches in length, 16 inches in height, and 8.5 inches in width. These dimensions allow it to sit securely within the driver-side wheel well without obstructing your tailgate operation.

Weight is listed at just 1 pound. This low mass means the hinge mechanism does not need to support a heavy load, which likely contributes to the smooth swinging motion. The box swings out nearly 180 degrees toward you. This range of motion allows you to access your cargo from the tailgate area without reaching over the side of the truck. It swings back into a locking position over the wheel well, keeping the bed clear for other uses.

Security is handled by a key-lockable lid. This feature prevents unauthorized access to your tools or gear. Inside, you will find an organizational tray. This layout helps keep smaller items from shifting during transit. A moisture seal is also included to help protect contents from rain and dust. The design maintains a 3-inch clearance from the truck bed. This specific gap ensures compatibility with virtually all tonneau covers, including soft, hard, folding, and rolling styles. You can install this box without removing your existing cover.

Setup And Everyday Use Guide

Installation involves mounting the unit to the driver-side wheel well of your 2017 through 2022 Ford F-250 or F-350 Super Duty. The design requires a specific 3-inch clearance from the truck bed surface. This measurement is critical because it determines compatibility with your existing tonneau cover. The listing states it works with virtually all soft, hard, folding, and rolling covers, provided that height requirement is met. You should verify your cover type before relying on this clearance.

Daily operation centers on the swing-out mechanism. The box rotates nearly 180 degrees toward you. This motion allows access from the tailgate area without needing to reach deep into the bed. Once you retrieve items, you swing the unit back over the wheel well. It locks into place to secure the storage space. The lid itself is key-lockable, adding a layer of security for your cargo.

Inside, the box holds up to 75 pounds of items. An organizational tray helps keep smaller tools sorted. A moisture seal is included to protect contents from the elements. While not fully waterproof, this seal helps keep items dry. The unit measures 34 inches in length, 16 inches in height, and 8.5 inches in width. Its lightweight construction, at just 1 pound, suggests it does not add significant bulk to your bed space. You simply load, swing, lock, and drive.

Before You Buy This Storage

You should verify your truck bed has at least three inches of clearance from the bed surface. This space is required for the unit to swing out fully without hitting your tonneau cover. The listing states it works with soft, hard, folding, and rolling covers. Check your cover’s specific dimensions to ensure no interference. You must also confirm your Ford F-250 or F-350 is a 2017 to 2022 model. This box mounts to the driver-side wheel well only. It holds up to seventy-five pounds, so distribute weight evenly. The moisture seal helps keep items dry, but it is not fully waterproof. You may want to add internal dividers for better organization. This unit complements most tonneau covers by freeing up bed space. It is a practical addition if you need secure, accessible storage. Ensure your current cover does not obstruct the swing path. Proper maintenance will keep the locking mechanism working smoothly over time.

Check before you buy

• Confirm 2017-2022 Ford F-250/350 Super Duty model year
• Verify three-inch clearance from bed surface for swing
• Check tonneau cover compatibility with 3-inch gap
• Ensure driver-side wheel well mounting space is clear
