Shield your cab and back glass from flying debris and low sun without boxing in your mirrors with the Weather Guard 11904-52-01 louvered aluminum headache rack. The louvered upper panel runs horizontal slats across the frame, so it blocks road spray, gravel and glare while still letting you see through to the rear cab window. It is built from corrosion-resistant aluminum with a matte black ARMOR TUF powder coat, mounts on the bed rails just behind the cab, and adjusts for height so the rack clears your cab on full-size pickups. Mounting brackets and hardware are included in the box, and the built-in accessory channel is ready for Weather Guard light brackets, cargo stops and tie-downs.
What's Included:
11904 louvered aluminum headache rack panel and frame
Two height-adjustable mounting legs
Bed-rail mounting brackets and installation hardware
Weather Guard assembly and installation instructions
Features
Louvered Panel Design Horizontal louver slats close off the middle of the cab window opening to stop road debris, gravel and low sun, while the louver gaps and the top window cutout keep some rearward visibility. It is the middle ground between the wide-open Open Frame rack and the full-coverage Hex mesh rack.
Corrosion-Resistant Aluminum The panel, frame and legs are formed from aluminum that shrugs off road salt, rain and jobsite weather without rusting like steel. Aluminum also keeps the rack light, so it adds cab protection without stealing much payload.
Matte Black ARMOR TUF Finish A matte black ARMOR TUF powder coat is baked over the aluminum to fight chips, fading and corrosion for years of hard use. The blacked-out look pairs cleanly with a Weather Guard crossover or side-mount box.
Height Adjustable For Cab Clearance The legs adjust up and down so you can set the panel to clear the back of your cab and line up behind the window on different full-size pickups. That adjustment is what lets one universal rack fit a range of trucks.
Built-In Accessory Channel An integrated channel along the rack accepts Weather Guard add-ons like light brackets, a cargo stop and tie-down accessories, all sold separately. You can add work lights or a beacon and strap long loads without drilling new holes in the rack.
Brackets Included, Limited Lifetime Warranty Unlike the older steel Protect-A-Rail cab protectors, this aluminum rack ships with its mounting brackets and hardware, so you do not have to buy a separate vehicle-specific kit. It is backed by a Weather Guard Limited Lifetime Warranty.
Fit guidance: This is a universal aluminum headache rack for full-size pickups, not a bolt-on for a single model. The mounting brackets and hardware are included in the box, so no separate vehicle-specific kit is required. The rack mounts on the bed rails just behind the cab and the legs adjust for height to clear your cab. Check the Weather Guard fitment guide for your exact make and model, and measure clearance behind the cab before ordering. It is not designed for mid-size or compact trucks.

Assemble the legs to the panel, set the rack on the bed rails just behind the cab, and secure it with the included brackets and hardware. Adjust the leg height so the panel clears the back of the cab and sits square behind the window, then torque the hardware evenly. A second person makes it much easier to hold the panel in place while you fasten the brackets. Follow the Weather Guard instructions for bracket placement and check the fasteners after the first drive.

Weather Guard Defender Series Truck Rack Install
Weather Guard's Defender Series install video shows the lightweight aluminum truck rack going onto a pickup with no drilling required. You see the compression clamps grip the bed rails and the crossbars set up to carry ladders, lumber and pipe, rated to about 800 pounds. It makes clear how quickly the rack mounts and how the ladder stops keep a load in place. It is a helpful look at the rack in place before you buy or install your own.
Weather Guard Steel Truck Rack Install
This official Weather Guard guide shows how to install a steel truck rack for hauling ladders, lumber and long loads over the bed. You watch the rack mount to the bed and get tightened down, with the load bars set for ladders and pipe. It gives a clear picture of how the rack goes on and how much it adds to a truck's hauling capability. It is the manufacturer's own reference for setting up the rack correctly.
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.
Frequently Asked Questions
Straight answers on specs, fit and support
Will the 11904 fit my truck?
It is a universal aluminum headache rack for full-size pickups such as the F-150, Silverado and Sierra 1500 through 3500, Ram 1500 through 3500, Tundra and Titan. The mounting brackets and hardware are included, so you do not need a separate kit. Check the Weather Guard fitment guide for your make and model and measure clearance behind the cab first. It is not made for mid-size or compact trucks.
What does the louvered design do compared to the other racks?
The louvered panel uses horizontal slats to block road debris, gravel and low sun while the louver gaps and top window cutout keep some rear visibility. It gives you more cab coverage than the Open Frame rack but a clearer view than the full Hex mesh rack, so it is the balanced choice in the lineup.
Does it come with everything I need to mount it, or do I need a separate kit?
Everything to mount it is in the box. This aluminum rack includes its bed-rail mounting brackets and hardware, unlike the older steel Protect-A-Rail cab protectors that require a separate vehicle-specific installation kit. Most installs take about 30 to 45 minutes with basic hand tools.
Can I add work lights to it?
Yes. The rack has a built-in accessory channel that accepts Weather Guard light brackets, a cargo stop and tie-down accessories, all sold separately. You can add work lights or a beacon and strap long loads without drilling new holes in the rack.
Will it rust?
It is built from corrosion-resistant aluminum and finished with a matte black ARMOR TUF powder coat, so it holds up to rain, road salt and jobsite weather far better than bare steel and will not rust like a steel rack.
Is it covered by a warranty?
Yes. The 11904-52-01 is backed by a Weather Guard Limited Lifetime Warranty against defects in materials and workmanship.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
