The Weather Guard 127-6-04" gunmetal gray splits the difference between bright aluminum and black with a modern dark-graphite ARMOR TUF finish. It is a distinctive, high-end look that still hides dirt and resists corrosion on the jobsite. Choose gunmetal gray if you want to stand out from the sea of plain black and silver boxes at the jobsite. It reads as a premium, almost factory-accessory color rather than a basic box. This full-size, standard aluminum saddle box straddles the top bed rails behind the cab and gives you 11.0ft³ of secured, weather-sealed storage without weighing down your payload. A 15-gauge aluminum, five-piece welded body with a reinforced C-channel lid and front keeps it strong yet light, and a full-perimeter D-shaped weather seal locks out rain and dust.
What's Included:
127 Series full-size standard aluminum crossover (saddle) tool box in gunmetal gray
1Key UltraLock push-button locks, keyed alike
Under-rail mounting clamps and hardware for a no-drill install
15-Gauge Aluminum Diamond-Plate Build This box is formed from 15-gauge aluminum in a five-piece welded body with a reinforced C-channel lid and front panel. It shrugs off jobsite abuse and road salt while staying lighter than comparable steel, so it will not weigh down your payload. This one is finished in gunmetal gray ARMOR TUF powder coat.
Gunmetal Gray ARMOR TUF Finish A gunmetal gray ARMOR TUF powder coat gives a modern, dark-graphite look that sits between bright aluminum and black. It hides dirt and light scuffs while resisting corrosion, fading and road salt.
1Key UltraLock Security Tamper-resistant push-button locks sit recessed when locked, giving a quick visual cue your gear is secured. The 1Key UltraLock system lets you code multiple boxes on a truck, or a whole fleet, to a single key.
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 The box straddles the top bed rails behind the cab, keeping your bed floor open for sheet goods and cargo. Enhanced tie-down buckles and 12V PowerSync-ready access round out a box built for working trucks.
Reinforced Body, Automotive-Grade Hardware Weather Guard specifies a five-piece welded body for the 127-6-04, with a C-channel reinforced front panel and a heavy-duty C-channel reinforced lid, so the box stays square when it is loaded and when someone stands on the lid. The latch is an automotive dual-stage rotary mechanism, the same style a truck door uses, so it pulls the lid down onto the seal instead of relying on a friction catch. A welded gas strut shield keeps loose tools from knocking the strut mount out of line. The D-shaped ribbed weather strip is memory resistant, so it springs back after years of closing rather than taking a set and letting water track in.
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. Always measure your bed rail width and check clearance behind the cab before ordering. It is not designed for compact or mid-size trucks.
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.
How the 1Key UltraLock System Works
A step-by-step look from Weather Guard at what the 1Key UltraLock actually does: how the cylinder accepts a new code, why the red push button retracts when the box is locked, and how the latch pulls the lid down against the seal. Worth two minutes before you set the box up.

Frequently Asked Questions
Straight answers on specs, fit and support
Will the 127-6-04 fit my truck?
It is a full-size standard 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 secure is this Weather Guard box?
It uses the Weather Guard 1Key UltraLock system with tamper-resistant push-button locks that sit recessed when locked, so you get a quick visual cue your gear is secured. The 1Key design also lets you code multiple boxes on a truck or a whole fleet to a single key.
Is the gunmetal gray finish durable outdoors?
Yes. The gunmetal gray ARMOR TUF powder coat resists corrosion, fading and road salt, and the full-perimeter D-shaped weather seal keeps water and dust off your gear. The mid-tone graphite color also hides dust and light grime between washes.
What does the gunmetal gray finish look like in person?
Gunmetal gray is a dark graphite tone, deeper than silver but lighter than black, with a subtle metallic look under sunlight. It is a distinctive, modern finish that pairs well with both light and dark trucks and hides dust between washes.
What is it made of and how big is it?
It is built from 15-gauge aluminum in a five-piece welded body with a gunmetal gray ARMOR TUF powder coat. The exterior measures 72"L x 20"W x 18"H with 11.0ft³ of storage, and it ships at about 80 lb, so it is strong yet lighter than a comparable steel box.

New Tool Box
Love the new matte black and textured paint. Overall, good box, but not built like they use to be. You can see where Weather Guard has tried to save money compared to their older boxes. I really like the tackle box added feature. An issue I’m having is the front part box lid sits about a half inch higher than the rear of the lid and the latches are not adjustable. The slidable try started flaking paint before I even installed it into the box. It’s a good box, but not worth the money.

I have a Chevy 2500Hd Crew Cab pick-up that I bought used. It had another brand relatively new tool box on it that did not fair well from use, so I replaced it with this Weatherguard. What a difference between the two! The weatherguard is light years ahead in strength and quality and made in the USA. The materials, construction and finish are first rate. The locking system is strong as heck, like your car door and looks nearly impossible to be forced open. I was very impressed with the large bearing area of the mounting brackets (included ) and quality bolts. The system securely fastens the box to your truck bed so you won't have to worry about a heavily loaded box walking around while driving. They recommend using a little lubricant on the mounting bolts to ease installation because the brackets have locknuts in them. I definitely agree you should follow that tip to save some busted…

For once, the engineers listened to the user. This is a well designed truck toolbox. Easy to mount with the included hardware. Looks awesome-started getting questions and compliments the first day it was mounted! Sturdy integrated tie down points that are reinforced. Smooth operating hardware. A good stiff lid thats easy to latch from the side. And there are some great add ons that take it up another level-remote lid popper and automatic LED lights can easily be added. And all of the hardware comes powder coated red to match the box.

Great box, so-so lock function
Very well build toolbox, but locks are not awesome. I can't say enough about how well built the structure is, it's like a tank and I expect it will last me for quite a long time. There isn't anything to complain about as far as the box function goes. My only issue is the locks. When you get it the keys are there but the actual locks aren't set and you do this by turning the new key 3/4 of a turn which sets the pattern, which is nice since you can key any new boxes to the keys you currently have. My only issue is the locks are very sloppy and you can feel it grating inside when you turn the key. My passenger side lock is decent but the driver side lock is very catchy and I have concerns that it'll last very long (or cause the key to eventually break).
