The Weather Guard 560-5-02 is a 60" underbed box, the longest standard-depth box in the steel line, putting 11.2ft³ of locking storage along the frame rail. Its 18" deep welded steel body runs five feet of rail, room for long tools, chains and a complete service kit under a flatbed, platform or dump body. A gloss black ARMOR TUF finish and heavy steel resist road salt and spray, and a weathertight drop-down door keeps gear dry. Mounting hardware is not included, so match it to your frame and support its length.

Features
Heavy Welded Steel Body The 560-5-02 is built from heavy welded steel, the toughest and most pry-resistant underbody box Weather Guard makes. It stands up to road spray, debris and the beating an underbed box takes on a work truck, keeping your tools secure and protected.
Gloss Black ARMOR TUF Finish A gloss black ARMOR TUF powder coat covers the welded steel to fight corrosion, chips and fading and give the box a clean, rugged black look. ARMOR TUF is Weather Guard's toughest coating, made to survive the salt, chemicals and weather an underbody box faces.
Weathertight Drop-Down Door A full drop-down door drops open on two support chains that hold it level as a handy work shelf, then closes against a rain gutter and full-perimeter weather seal. Your tools stay dry and protected from road spray, dust and debris in the 11.2ft³ interior.
Stainless Locking Latch, Three-Point Latching A stainless steel locking compression latch drives a three-point latching system with a drill-resistant lock core, so gear stays secure and the door pulls tight against the seal. The latch is easy to work even with gloves on.
Tool-Less QuickClip Door The drop door adjusts from 90 to 180 degrees and pops off with QuickClips, no tools required, so you can drop it flat, use it as a loading shelf, or remove it entirely for full access and clip it back on in seconds.
Mounts Under the Deck, Frees Your Truck The standard 18" deep body mounts on the frame rail below a flatbed, platform, service or dump body, so heavy tools and equipment ride secure and out of the way while your deck or bed stays open. It is the way to add locking storage to a truck with no usable bed floor. Mounting hardware is not included so you can match it to your frame.
Gloved-Hand D-Handle and a Wide Door Opening The drop door opens wide, so long tools and cases go in from the side of the deck instead of being lifted over a lip. Weather Guard fits a stainless steel D-handle that is easy to grip with gloves on and pulls the door tight against the seal, and the door itself drops level on its chains to work as a shelf.
Fitment & Compatibility
Application

Service and utility body trucks, enclosed trailers

✗ No, this box mounts below the bed on the frame, not on the bed floor
Fit guidance: Underbed boxes mount on the truck frame rail below the deck of a flatbed, platform, service or dump body, or under a pickup bed where there is frame space. Fit is by available space and mounting, not by year, make and model. This box is 60" long and 18" deep, and the drop door needs room to swing down below it. Always measure the clear length along your frame rail and the drop clearance before ordering. Mounting brackets and hardware are not included, so plan to supply frame-appropriate mounting hardware.

Choose a clear spot on the frame rail below the deck with room for the door to drop open, then mount the box to the frame using brackets and hardware rated for the load (not included). Support the box while you fasten it, and seal any drilled holes with zinc-rich primer to prevent rust. Follow the Weather Guard Aluminum and Steel Underbed Boxes installation manual for hole layout and best practices. Because the box hangs below the deck, use hardware and brackets sized for the weight of the box plus its contents.

Best Upgrade for Your Truck
This is Weather Guard's own brand film about outfitting a working pickup, built on the idea that the truck should already be loaded and organized before the day starts. It puts the bed and rail equipment in the context of a real work day rather than a spec sheet.
Watch it if you are still deciding how much storage a truck actually needs. It is the clearest short look at how Weather Guard boxes, racks and drawer units are meant to work together on one vehicle, and it comes straight from the manufacturer rather than a reseller.
Frequently Asked Questions
Straight answers on specs, fit and support
Where and how does this box mount?
It bolts to the frame rail below the deck of a flatbed, platform, service or dump body, or under a pickup bed with frame space. At 60" it needs a long, clear run of rail and support along its length. Mounting brackets and hardware are not included, so choose hardware rated for the box plus its contents.
Will it fit my truck?
Fit is by frame-rail space, not year, make and model. The 560-5-02 needs about 60" of clear rail and 18" of depth, plus room below for the drop door. Measure the full 60" clear rail length and the drop clearance before ordering.
Is this steel or aluminum?
This is the welded steel version, the toughest and most pry-resistant underbody box Weather Guard offers, and it weighs about 135 lb. Steel is a great choice for heavy-duty service, flatbed and dump trucks. Weather Guard also builds underbed boxes in lighter aluminum diamond plate if saving weight matters more.
What is the gloss black finish like?
The welded steel body wears a gloss black ARMOR TUF powder coat that resists corrosion, chips and fading and gives a clean, rugged look. Wipe it down with mild soap and water to keep the black finish sharp.
How does the door work and is it weathertight?
A long drop-down door lowers on two support chains to sit level as a work shelf the length of the box, seals against a rain gutter and full-perimeter gasket, and locks with a stainless compression latch and three-point latching. The 11.2ft³ interior stays dry and secure, with room for long tools and a full service kit.
Is it made in the USA and under warranty?
Yes. The 560-5-02 is made in the USA and backed by a Weather Guard Limited Lifetime Warranty against defects in materials and workmanship.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
