The Weather Guard 117-0-03 is the previous-generation full-size extra-wide aluminum saddle box, offered here as the proven, value-priced pick that came before the current 1Key UltraLock update. It locks down with the One Key push-button high-security lock, coding multiple boxes on a truck or a whole fleet to one key and staying PowerSync capable for Weather Guard interior lights and remote keyless entry accessories. The body is a five-piece welded aluminum diamond plate sealed under a clear ARMOR TUF coat, giving that classic, high-visibility bright-aluminum look while staying lighter than steel and immune to rust. Set across the top bed rails behind the cab, it opens to 14.4ft³ of weather-sealed storage and keeps the bed floor clear underneath. A reinforced lid on gas struts and a full-perimeter D-shaped weather seal keep water, dust and road salt off your tools in any weather.
What's Included:
117 Series full-size extra-wide aluminum crossover (saddle) tool box in bright aluminum
One Key push-button high-security lock, keyed alike
Under-rail mounting clamps and hardware for a no-drill install
Welded Aluminum Diamond-Plate Build A five-piece welded aluminum diamond-plate body with a reinforced C-channel front panel keeps this box strong yet light. It resists jobsite abuse and road salt without adding the weight of a steel box. This one is finished in clear ARMOR TUF powder coat over bright aluminum diamond plate.
Bright Aluminum Clear ARMOR TUF Finish A clear ARMOR TUF coat seals the raw aluminum diamond plate yet lets the bright, traditional work-truck shine come through. It shrugs off corrosion, road salt and fading, and the diamond-plate texture helps light scuffs blend in instead of standing out.
One Key Push-Button High-Security Lock This redesigned saddle box uses a push-button high-security lock that codes multiple boxes on a truck or fleet to one key, and it is PowerSync capable for Weather Guard interior lights and remote keyless entry accessories.
Full-Perimeter Weather Seal A memory-resistant D-shaped, multi-ridge weather strip runs the entire lid perimeter to keep rain, dust and debris off your tools, so your gear stays dry and ready in any weather.
Reinforced Lid With Gas Struts Gas struts hold the reinforced lid open near 90 degrees for easy one-handed access, and welded strut shields protect them from damage. The steel-reinforced lid resists flex and stands up to daily use.
Saddle Fit Across The Bed By straddling the two bed rails behind the cab, the box leaves the bed floor wide open for plywood, ladders and long cargo. Enhanced tie-down buckles anchor loose loads and a 12V PowerSync-ready port supports interior lighting and electrical upfits.
Fit guidance: Crossover, or saddle, boxes mount across the truck bed on top of the two bed rails just behind the cab, so the box straddles the bed and leaves the bed floor open. At about 72" wide this size fits standard-width full-size pickups, and because it sits on the rails rather than the bed floor it works with short, standard and long beds on those trucks. This is an extra-wide box, so it needs a full-width full-size bed and will reduce side-to-side reach past the box. Always measure your bed rail width and check clearance behind the cab before ordering. It is not designed for compact or mid-size trucks.
Mounting: Under-rail clamps and hardware included, no drilling required
Electrical: 12V PowerSync compatible access
Weight: About 82 lb (shipping weight)
Warranty: Limited Lifetime
Made In: USA
Installation
Type: Saddle mount across the top bed rails, clamp-in with no drilling · Time: About 20 to 30 minutes · Tools: Socket or wrench set and a tape measure; no drill needed with the included under-rail clamps · Difficulty: Easy, best done with two people for the lift
Set the box across the two bed rails behind the cab and center it left to right. Hook the included clamps under each bed rail and tighten the hardware evenly so the box sits flat and the lid seals all the way around. Because the box is wide, have a second person help lift and hold it while you clamp it down. Follow the Weather Guard installation instructions for exact clamp placement and torque.

Weather Guard's official hardware video zooms in on the clamp and bolt kit that secures its truck boxes to the bed rails without drilling. It is a helpful close-up companion to the full box install and shows how the mounting brackets hook under the rail lip and tighten down. Use it alongside the printed instructions that ship with the box.
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 Replace the Lid on a Saddle Truck Box
Weather Guard's step-by-step guide to taking the lid off a saddle truck box and fitting a replacement. It covers the hinge and strut hardware that carries the lid, which is the part that takes the abuse on a box that gets opened twenty times a day.
Keep it bookmarked rather than watching it now. It is the reference you want the day a lid gets damaged on the job, and it comes straight from the manufacturer so the hardware and the sequence are correct.

Frequently Asked Questions
Straight answers on specs, fit and support
Will the 117-0-03 fit my truck?
It is a full-size extra-wide crossover, or saddle, box that mounts across the top bed rails behind the cab, so it fits full-size pickups such as the F-150, Silverado and Sierra 1500 through 3500, Ram 1500 through 3500, Tundra and Titan. It needs about 72" of rail-to-rail width. Measure your bed rails and check clearance behind the cab first, and note it is not designed for compact or mid-size trucks.
Does it require drilling to install?
No. The box ships with under-rail clamps and hardware, so it mounts without drilling into your truck. Most installs take about 20 to 30 minutes and go easiest with two people to lift and hold the box while you clamp it down.
How does the lock on this saddle box work?
This earlier-generation saddle box uses a One Key push-button high-security lock. Press the button to release the lid, and the keyed cylinder lets you code several boxes on one truck, or an entire fleet, to a single key. It is PowerSync capable as well, so it pairs with Weather Guard interior lights and remote keyless entry accessories.
How does the bright aluminum hold up outdoors?
Very well. Aluminum will not rust the way steel can, and the clear ARMOR TUF coat plus the full-perimeter D-shaped seal keep water, road salt and dust off your gear and the finish. A rinse and a wipe are usually all it takes to bring the diamond plate back to a bright shine.
Is this an earlier-generation box, and why does it cost less than the current model?
Yes. This is the previous-generation 117 saddle box, running the proven One Key push-button high-security lock and PowerSync wiring rather than the newer 1Key UltraLock hardware on the current version. The welded aluminum diamond-plate body, full-perimeter weather seal and no-drill mounting carry over unchanged, so you get the same everyday performance at a lower, value price.
What is it made of and how big is it?
This previous-generation box is five-piece welded aluminum diamond plate under a clear ARMOR TUF coat. It measures 72"L x 27-1/2"W x 18-1/2"H, holds 14.4ft³, and ships at about 81.56 lb, so it stays much lighter than steel while giving you a value price.

Disappointed
117-52-02 on a 2017 F-350. Been using Weatherguard products for decades and very disappointed in this box. As other reviews have said you have to get into the bed and push this lid from the center to get this box to positively latch on both sides. Even with a 3rd step on my truck and stretching acoss the box and slamming it will not close the opposite latch.

Highly recommend this extra wide tool box!
What a great tool box for my truck! Put it in a 2023 chevy 1500 to store all the stuff I need to carry gear for my guys onsite. Really really happy I got the extra wide box. It makes such a big difference. It's got some great weather seals that keep all my stuff dry. I even tried giving it a few deliberate sprays when washing the truck to test it and it stayed dry. The locks are great in that you can unlock one side (and leave the other locked) and open the tool box. They are also conveniently located so you don't have to get into the bed of the truck to open the box or lock/unlock it. When I need another box for new trucks I will definitely be getting another one of these. HIGHLY RECOMMEND.

This is by far the best toolbox that I’ve owned. It’s light weight but really well built and has exellent locking latches. The push button feature is also very nice. I’ve had mine on my truck for over a year now and the powder coat finish still looking brand new. Overall it’s money well spent.

Great, well built toolbox! I’m in the land clearing and site work business, so I carry as many tools that I might need as I can. My old, standard sized toolbox allowed for a lot of it, but it was so disorganized and cluttered that it took me longer to find something than it did to fix it. This toolbox resolved that issue for me and allows me to carry it all and in an organized way. I love it!

Nice box . Small issue with the latch, easy fix.
Nice well made toolbox. When I programmed the keys, the latch would not unlock. Figured out the latch pushrods needed to be shortened about 1/8” . After that, everything was good. No complaints.

excellent tool box
Tool box is well built, heavy duty. I have owned numerous weatherguard boxes before and they all work well for the demanding professional or serious truck lover. 4 stars due to the fact that it takes some love to make it latch. havent had time to tinker with it but assume the gaskets are tight and latches need to be adjusted to make it work correctly..Well Worth The Money overall!
