The Weather Guard 116-3-03 is the previous-generation full-size extra-wide steel saddle box, offered here as the proven, value-priced choice that came before the current 1Key UltraLock update. It secures your gear with the One Key push-button high-security lock, which codes multiple boxes on a truck or across a fleet to a single key and stays PowerSync capable for Weather Guard interior lights and remote keyless entry accessories. The heavy-duty formed steel body wears fleet-friendly brite white ARMOR TUF powder coat that reflects heat, resists rust and chips, and matches a white work truck without extra paint. Straddling the top bed rails behind the cab, it delivers 14.5ft³ of weather-sealed storage while leaving your bed floor open for sheet goods and cargo. A reinforced lid on gas struts and a full-perimeter D-shaped weather seal round out a box built to earn its keep season after season.
What's Included:
116 Series full-size extra-wide steel crossover (saddle) tool box in brite white
One Key push-button high-security lock, keyed alike
Under-rail mounting clamps and hardware for a no-drill install
Heavy-Duty Steel Build A heavy-duty formed steel body with a reinforced lid and front panel stands up to years of loading, weather and road abuse. Steel gives this box maximum strength and a solid, secure feel. This one is finished in brite white ARMOR TUF powder coat.
Brite White ARMOR TUF Finish Brite white ARMOR TUF powder coat bounces sunlight away so the box and the gear inside run cooler on hot days, and it drops straight onto a white work truck or van fleet with no repaint. The baked-on coating fights rust, chipping and yellowing through years of loading and weather.
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 148 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 116-3-03 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.
Does the white finish stay clean and hold up over time?
It holds up well. The brite white ARMOR TUF powder coat is baked on to fight rust, chipping and yellowing, and the full-perimeter D-shaped seal keeps water out of the box. White does pick up road grime faster than a dark box, but a quick wipe brings it back, and the light color reflects heat to keep tools cooler inside.
Is this an earlier-generation box, and why does it cost less than the current model?
Yes. This is the previous-generation 116 saddle box, built around the proven One Key push-button high-security lock and PowerSync wiring instead of the newer 1Key UltraLock hardware on the current version. The heavy-duty steel body, full-perimeter weather seal and no-drill mounting are the same rugged design, 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 heavy-duty formed steel under a brite white ARMOR TUF powder coat. It measures 72"L x 27-1/2"W x 18-1/2"H, holds 14.5ft³, and ships at about 147.96 lb, so it brings serious steel strength at a value price.

Perfect Fit
This is my first saddle box: with a single 'chest-type' hinged top door. My previous work trucks equipped with cross-bed tool boxes always had gull-wing top doors. The large top door on this box gives good access to a huge storage space, and the latches close securely with a positive click by merely pressing firmly in either back corner of the lid. Even minus 30* temps and 12" of snow, this box remains dry and weather-tight. The paint finish is very good; one corner of the lid got nicked, repaired with sandpaper and white nail polish ;-) The keyed-alike locks work perfectly and the hooks on the back of the box are quite handy for securing larger loads like furniture. Overall this toolbox has met and exceeded all my requirements. Further, l expect it will serve me well into the future.

Not overly impressed
Does not come with carpet or a lining. Does not come with foam for the bed rails. I needed a box that has side lock buttons. Decided on the weather guard based on a had one years ago and it was awesome. Quality of this one for the money spent just isn’t worth it.

Best toolbox I've ever owned.
This toolbox really surprised me. I expected the lid to be flimsy like most toolboxes, but when you push down on one corner to close it, both sides latch. I weigh 250 lbs and can stand on the lid, hop up and down, and it doesn't give at all. The powdercoat is tough and cleans up really well. If you want a secure toolbox that will hold up to thrives and look great, buy this.

Great toolbox! Lots of room to store important items. The only thing we did not pay attention to when purchasing was that it is a very wide box. In a regular or short bed truck, this will not allow the ladders to reach the headache rack with the legs touching the bottom of the bed. But that's okay!

Theft Protection
After being hit by thieves twice it has become apparent that thieves are now collecting Weatherguard keys. Both times access was gained without forced entry. Consequently this renders the box useless for tool security. I suggest a different box or adding additional hasps and locks.

The strength and build of this box is very good. No trouble with the install other than trying to reach the mounting hole closest to the cab of the truck. I hadTo use the two furthest away from the cab. I bought a rubber floor pad to line the bottom so cargo would not bounce around.

We have had 3 of these in our life. We bought the first one about 15 years ago. We are a construction worker and it gets MAJOR use. Our first one needs a new latch and new shock absorber on one side. Not sure how to get that replaced. Bought our second one a year ago and 3rd one a month ago for our employee. We like that its BIG, holds a lot of tools and doesnt rust out. 4 star only because the welds broke on the 15 year old because the latch broke, the welds broke on back hinge and shock absorbers wore out. And its hard to get parts... actually, we havent figured out how to get replacement parts. But again, ours gets MAJOR use. so its the cadilac for average usage.

This box is well worth the money. The only problem is I live in NJ and we get a lot of rain. The bed box got rust in the right rear corner where the weather striping did not full protect.

You Get What You Pay For
This box was easily double the price of the "bargain brands" but the quality, craftsmanship and finish details are worth every penny. The full-length lid clicks shut securely from either side. Of course the storage space is gigantic. I worked construction for 21 years and used 3 different non-name-brand boxes, on 2 different trucks. This is the box I saw on some of the nicer contractors' trucks. Now I know why...Anyhow, I got what I wanted. Also, I got what I paid for: the nicest cross-bed tool box on the market. Don't forget the lifetime warranty. Yeah, you definitely get what you pay for with Weather Guard.

Heavy Duty But Expensive
Purchased for my F250 which will solely be used for travel trailer towing. The extra wide tool box is perfect for storing miscellaneous tools and trailer set up equipment. It's obviously designed and manufactured as a heavy duty unit for the working person which can be expected to use and abuse the box in the course of their trade. I like the fact that it has a flat to satin black finish (and not a high gloss finish as advertised). The reason for the 4 star review is the powder coat actually has some paint runs, some metal panels are slightly warped / bowed, and some other finish imperfections. Was hoping the surface finished quality was better as it goes on a brand new truck, but again, this is for the working person (not an old retired one like me). For the expensive price of the box, the finish could of, and should of, been better.
