Features

  • 14-gauge steel body: The top and sides are 14-gauge steel on 12-gauge skids, reinforced so the unit keeps taking hard use for years.
  • 425 lb drawer capacity: Every -04 drawer is rated for 425 lb, so the whole kit can come to the job instead of half of it staying home.
  • Heavy-duty top load: The deck carries 750 lb on the 10.25", 20" and 30" wide units and 2,000 lb on the 39.75" and 49.5" wide units, so the bed above the drawer keeps hauling.
  • 1Key UltraLock: The factory-fitted 1KEY ULTRALOCK runs on the same key as your other Weather Guard 1Key gear, so one lost key never leaves the crew locked out.
  • Adjustable partitions: The drawer spans the full width of the unit, and removable partitions (on all but the narrow 305 and 335) plus dividers let you lay it out around your tools.
  • Full extension, easy pull: The drawer rolls out to its maximum extension, and the full-width handle makes it smooth to open even when the drawer is loaded.

Description & Fitment

Sized at 48" long and 20" wide, the 336-3-04 is a 13" tall steel Pack Rat finished in white. Weather Guard lists it at 176 lb, with a 45" D x 19.5" W x 8.5" H drawer that holds 425 lb and a top that takes 750 lb; inside you get 1 removable partition plus 6 narrow and 3 wide dividers.

About Weather Guard

WEATHER GUARD.

Weather Guard is the truck and van storage brand of Werner Co., the Illinois company also known for its ladders. Its tool boxes are built in the USA, and the line runs from crossover, Lo-Side and gull-wing boxes to chests, underbody boxes, bed drawers, transfer tanks, ladder racks and van shelving.

Weather Guard's current boxes use the 1Key UltraLock, a red push-button lock you can code so one key opens every box on a truck or across a fleet, and many are finished in ARMOR TUF powder coat.

Buying Weather Guard from Prestige Truck. Weather Guard asks for the original sales receipt with any warranty claim, so keep your Prestige Truck order receipt with your records.

Frequently Asked Questions

Will it fit an F-150?

That truck is on our fitment list for this unit. Measure your bed floor against the 48" length and 20" width before ordering, and leave room for the drawer to roll out.

How much can the top carry?

Weather Guard rates the top of the 336-3-04 at 750 lb and the drawer at 425 lb, so you can keep hauling cargo on the deck while the tools ride below.

Do I have to drill my truck?

Yes. Weather Guard's sheet bolts the housing down through holes you drill, using blind fasteners that you seat with the supplied tool and two wrenches. Check there is enough hole depth first, and in an aluminum bed coat the holes with zinc-rich primer and fit a plastic washer on each side of the fastener.

How does the 1Key UltraLock work?

The lock comes fitted at the factory and works on the same key as Weather Guard's other 1Key UltraLock products. Weather Guard's point is that if one key goes missing, the rest of the crew can still open the gear.

What should I not keep in it?

Weather Guard's sheet warns against storing flammables, explosives or hazardous materials, naming gasoline containers, solvents, propane and acetylene tanks and cutting torches. Keep it to tools and equipment.

Can I move the partitions?

Yes, on units with removable partitions. Take out the partition's two 1/4-20 bolts with two 7/16" wrenches, swing it clear of the rear slots and lift it out; refit it the same way in reverse.

Installation

Install time Not printed on Weather Guard's install sheet
DifficultyNot printed on Weather Guard's install sheet
TypeFloor-mount drawer unit, bolted to the bed floor through drilled holes with blind fasteners (Weather Guard installation instructions for the 305-X-04 to 3713-X-04 Pack Rat units)
Toolselectric drill with 3/8" and 1/2" bits, 1/2" and 9/16" open or box wrenches, a ratchet with a 1/2" socket, a common screwdriver and zinc-rich primer

Here's the short version. Follow Weather Guard's install sheet (below) for the exact positions and hardware.

  1. The drawer unit is heavy: team lift it, or use a forklift or overhead hoist, and set the housing in the bed as shown on p3.
  2. Drill the mounting holes and set the blind fasteners: oil the black oxide bolt, hold the installation tool with a 9/16" wrench and turn the bolt with a 1/2" wrench until the fastener is fully seated.
  3. Check there is enough hole depth before setting each blind fastener.
  4. Aluminum bed: prime the holes with zinc rich primer and put a 1/2" x 1" plastic washer on each side of the blind fastener.
  5. To move the adjustable partition, remove its two 1/4-20 bolts (two 7/16" wrenches), swing it free of the rear slots and lift it out. Refit in reverse.

Beast of a Toolbox

I've owned my box for over 10 years. I am a Industrial hydraulic mechanic primarily dealing with Oil Drilling rigs & paper Mills. So big tools and big parts. I loaded my box with all my big wrenches up to 3" and sockets up to 5". I also had my big pipe wrenches. Plus all my odds and ends. I'd stack hydraulic winches on top. Roughly 400 lbs ea. I had 4 on top at one time. It would take a beating and never fail. As most field mechanics know. Tool boxes don't last in the back of the bed. Just the road vibrations and bouncing destroys them. Go ahead and spend the money and get you the box that will last forever.

Best purchase I’ve made in a long time. I have to carry a lot of tools in my truck and this made it 10x easier. No more climbing in bed of truck to grab tools. I was also able to keep my Weatherguard toolbox in truck. This was a great addition to my work truck.

This is the best, lockable storage without a cap

I used this product back in 1997 and it served me well in my job. I changed some rollers and repainted and re did the grip strips. I eventually put on a topper to keep things dry which kept it like new. I am considering a new one for my next truck just for the convenience and weight even though I am retired.

Perfect bed organizer

This tool box is great. Its so much better than just a typical bed tool box that everything just gets dumped into and the organization is well lacking. With the Pack Rat, everything stays organized, neat and clean. I never have to jump into the bed searching for a tool or item either. The box locks up so there is no worry about my stuff getting jacked. The grip tape they use on top of the box incredibly grippy also. Installation was easy and straight forward. I live in Florida and we havent had a ton of rain yet, so I cant comment on the box keeping water out, but between car washes and what rain we have had, my tools have stayed dry.

Doesn't Rattle!

I choked on the price and was afraid that it would rattle...as it weighs so much. I'm pleased to report that I've had it mounted and running in a small pickup (tacoma) for weeks with not a single complaint. There are a could of features that are a little odd. The pin that fastens the drawer shut is square and you have to push the button down to shut the unit. This may be a safety device forcing you to think through shutting the drawer and consciously pushing the button to close the heavy drawer. I'm a fly fishing guide and get compliments on the level of organization and sturdy appearance. Love this thing. Kept me from having to get a shell for my truck.

No organization extras

So I'm an automation tech and this is an awesome tool and parts storage idea. I rated low on features because I can not find any sort of drop in tool organizers. If the company would come up with accessories to organize tools such as sockets, wrenches, and other hand tools this would put the company on top of the world.
