Give your work truck a classic, high-visibility look with the Weather Guard 127-0-04" bright aluminum diamond plate. Its clear ARMOR TUF powder coat lets the raw diamond plate shine through while sealing the aluminum against corrosion, fading and road salt. If you want the traditional, high-visibility look most buyers picture on a work truck, bright aluminum is the go-to choice. Scratches and swirl marks also tend to blend into the diamond plate instead of standing out. 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 bright aluminum
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 clear ARMOR TUF powder coat over bright aluminum diamond plate.
Bright Aluminum Clear ARMOR TUF Finish A clear ARMOR TUF powder coat protects the raw aluminum diamond plate while keeping that bright, traditional work-truck look. It resists corrosion, road salt and fading without hiding the diamond-plate texture.
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 127-0-04, 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.

Frequently Asked Questions
Straight answers on specs, fit and support
Will the 127-0-04 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.
How does the bright aluminum hold up outdoors?
Very well. The aluminum body will not rust like steel, and the clear ARMOR TUF coating plus the full-perimeter D-shaped weather seal keep water, salt and dust out while protecting the finish. A rinse and a wipe keep the diamond plate bright.
Does the clear aluminum finish need much upkeep?
Not really. The clear ARMOR TUF powder coat seals the aluminum, so it will not rust like bare steel and it wipes clean with mild soap and water. The bright diamond plate hides light scuffs well and keeps its look with basic care.
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 clear ARMOR TUF powder coat over bright aluminum diamond plate. 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.

Mounting of box was easy and quick. Very nice workmanship and quality materials. Takes more force to close than my other boxes but also a waterproof box not just " weather resistant." The tray is nice however the passenger side lockup to keep it from sliding back and forth isnt bent right so will not lock in on that side. Overall great box by far best ive had yet.

Great quality product. You have the set anchors, two keys and an accessories tray inside the box. You have a lock on both sides of the box which makes it great. Setting it inside the bed of the truck and getting it tightened down accordingly was easier than I expected. I couldn’t be happier with the quality and ease of installation, definitely recommend.

Post Install Review
Read other reviews about the nuts and bolts of the mounting hardware not matching. Figured this was some kind of random mistake. Sure enough that is exactly what happened when I started installing this box. Ended up buying a 5/16-18 tap to re-tap the nuts that are attached to the hook part of the hardware. Also, when I use the passenger side latch to open the lid, it will not re-latch. The driver side latch has to be re-pressed, upon which there is a loud clunk, then the lid will re-latch. Read another review where someone had this same problem. Hopefully I can adjust the latches to get both of them working properly. Overall, the box does seem pretty solid, but I am somewhat disappointed that when you spend top dollar for an item, you run into a problem like this that should have been resolved at the factory. Those couple things aside, I am glad I went with the Weatherguard box. Though…

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.

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).
