Features
Huge 18.6ft³ Extra-Wide Capacity At about 62" long by 27" wide, the 685-3-01 holds a massive 18.6ft³ of tools and gear, the most storage in the All-Purpose Chest range.
Angled Body for Fifth-Wheel and Gooseneck The angled body design is ideal for fifth-wheel and gooseneck trailer setups, letting you carry maximum storage in the bed while leaving room around the hitch.
Offset-Hinge Zero-Clearance Cover The offset-hinge design lets the back of the chest sit tight against the front of the bed because the cover needs zero clearance to open a full 90 degrees, so you use every inch of bed length.
Automotive Rotary Latch and Weather Seal An automotive-style rotary latch pulls the cover tight against a full weather seal every time you close it, keeping rain, snow and dust out of your tools.
12V Access A 12-volt access port makes electrical up-fits simple for lighting or charging accessories inside the chest.
Heavy Steel, White ARMOR TUF Finish A heavy steel body gives extra strength and dent resistance for demanding fleets, and a bright white ARMOR TUF powder coat resists corrosion and fading. Made in the USA.
Fitment & Compatibility
Truck or Application
Fit
Full-size trucks with fifth-wheel or gooseneck setups
✓ Yes, ideal application
Full-size trucks, trailers and flatbeds
✓ Yes, if the bed is wide enough for the 27" width
Mid-size and compact trucks
✗ No, the extra-wide 62 x 27" footprint needs a full-size bed
Fit guidance: The 685-3-01 is an extra-wide chest, about 62" long by 27" wide by 19-1/4" tall, so it needs a full-size bed with the width to accept a 27" footprint. Its angled body is designed for fifth-wheel and gooseneck trailer applications. The offset-hinge cover opens with zero clearance behind it. Measure your bed width and length carefully before ordering.
Best For: Fifth-wheel and gooseneck trailer applications
Weight: About 103 lb (134 lb shipping)
Made In: USA
Warranty: Limited Lifetime
Installation
Type: In-bed, set against the bulkhead and secure · Time: About 20 to 40 minutes · Tools: Tape measure and a wrench or socket set; tie-down straps or the included hardware · Difficulty: Easy to moderate, best with two people for the lift
Set the chest in the bed against the front wall. Because of the offset-hinge zero-clearance design, the back sits tight against the bed front and the cover still opens a full 90 degrees. Secure it with straps or bolt-down hardware per the Weather Guard instructions and confirm the weather seal closes all the way around.

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.
Weather Guard Truck Box Lineup and 1Key UltraLock
This official Weather Guard overview tours the current truck box lineup and the 1Key UltraLock security system that runs across it. You see how one coded key can open every Weather Guard box on the truck, from saddle to lo-side to hi-side, with a pop-up red button that tells you at a glance whether a box is locked. It highlights the sloped, reinforced lids and the ARMOR TUF powder coat that let these boxes shrug off weather and jobsite abuse. If you run more than one box, or a whole fleet, it shows why keying everything alike saves time every day.
How to Code Your 1Key UltraLock
Weather Guard's own step-by-step guide shows exactly how to program the 1Key UltraLock on a current 04 Series box. You watch the simple coding sequence that locks every box on your truck to a single key, so you carry one key instead of a ring full. It is the clearest reference for setting up your lock the first time and for adding more boxes to the same key later. Keep it handy when your box arrives, since the locks ship uncoded and are set on first use.

Frequently Asked Questions
Straight answers on specs, fit and support
How much does it hold?
The 685-3-01 holds a huge 18.6ft³, the most in the All-Purpose Chest range, thanks to its extra-wide 62 by 27" steel body.
Is it good for a fifth-wheel or gooseneck truck?
Yes. Its angled body design is made for fifth-wheel and gooseneck trailer setups, so you can carry maximum in-bed storage while keeping room around the hitch.
Why does the cover need zero clearance?
The offset-hinge design lets the cover open a full 90 degrees without needing space behind it, so you can push the chest tight against the front of the bed and still use the full bed length.
Will it keep my tools dry?
Yes. An automotive-style rotary latch pulls the cover tight against a full weather seal every time you close it, keeping rain, snow and dust out.
Will it fit my truck?
It is extra wide, about 62" long by 27" wide by 19-1/4" tall, so it needs a full-size bed wide enough for the 27" footprint. Measure your bed width and length before ordering; it is not for mid-size or compact trucks.
What is it made of and is it under warranty?
It is built from heavy steel with a bright white ARMOR TUF powder-coat finish, made in the USA, and backed by a Weather Guard Limited Lifetime Warranty against defects in materials and workmanship.

Perfect for securely stowing camping gear. More room than the standard cross-bed boxes that sit on top of the bed rails. This is one well made tool box!

Weather Guard tool boxes are the best built boxes I’ve encountered. The 62” all purpose chest has huge capacity, but it should be noted that these will not mount directly into most supercab or super crew pickups without a retrofit; I had to lift mine 7 inches to clear the humps in the bed.

So far so good. Easy to install. It was great that all the fasteners I needed were sent with the box. I will be able to give a more accurate rating after I've had this box for more than 3 months.

Weatherguard truck toolbox chest
Instructions could have been a little better, but overall acceptable. Chest itself is solid and after multiple days of rain still dry inside. Seems very solid. A little difficult to have latch from side/ground, but can do.

This is our second weather guard chest, and there is no comparison. Sits flush with bed rails and pushes tight up to the front of the pickup bed unlike cheaper brands that need to have 3 to 4 inches of gap from the front.
