Features
- 1Key UltraLock: Weather Guard's 1Key UltraLock lets you code the key to this box alone or to every 1Key UltraLock box on the truck or in the fleet, so a single key on your ring opens them all.
- Push-button lock: The lock is a red push-button built to resist tampering, and Weather Guard says the button shows you at a glance whether the lid is locked or open.
- Full weather seal: A memory-resistant, D-shaped ribbed weather strip seals the lid, keeping rain, road spray and dust off the tools inside.
- Easy-close latch: Automotive-style dual-stage rotary latches catch with less effort, so the lid shuts without a hard slam.
- 12V access port: A 12V access point lets you bring power into the box for whatever electrical up-fit your work calls for.
- Enhanced tie-down buckles: The tie-down buckles have extra clearance, so a universal strap, or several straps at once, can hook on to hold cargo against the box.
Description & Fitment
This gloss black 18-ga steel saddle box, part 128-5-04, is the full-size deep model in Weather Guard's 1Key UltraLock line. At 151.5 lb, it gives you 15.0 ft³ of space in a body that measures 72" L x 20" W x 24" H. The steel body is 66.5 lb heavier than the aluminum 123 twin, in 18-ga steel.

Check your fit: a full-size pickup on Weather Guard's Truck Fit Guide for the 128 size: Silverado 1500/2500/3500 6½' and 8'; Ram 1500/2500/3500 8'; F-150 6½' and 8'; Super Duty F-250/F-350 6¾' and 8'; Sierra 1500/2500/3500 6½' and 8'; Titan 5½', 6½' and 8'; Tundra 5½', 6½' and 8'. The guide covers 2018 and newer trucks, and Weather Guard asks you to measure your bed rails before ordering.
Not for: mid-size pickups (Weather Guard's 62" mid-size 131, 137, 154 and 156 boxes are sized for them); Silverado 1500/2500/3500 5½'; Ram 1500/2500/3500 5½' and 6'; F-150 5½'; Sierra 1500/2500/3500 5½' beds, which the guide does not list for this size. Other 128 parts: 128-3-04. Same size in aluminum: 123-0-04, 123-5-04, 123-52-04, 123-6-04. Not included: zinc-rich primer, which Weather Guard calls for on any holes drilled into an aluminum bed.
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 a Chevrolet Silverado 1500 6½' bed?
Yes. Weather Guard's fit guide lists the 128 size for that truck and bed, along with 14 other truck and bed pairings. Measure your rails to confirm.
Will it fit my Colorado or Ranger?
No. This is a 72" full-size box. For mid-size beds, Weather Guard makes 62" crossover boxes such as the 131, 137, 154 and 156.
Can one key open all my boxes?
Yes, as long as they are 1Key UltraLock boxes. Weather Guard lets you code the key to one box or to as many as you need. Write your key code down: the install sheet says there is no way to look it up if it is lost.
Do I have to drill my truck bed?
Not on a standard install. The box rests on both rails and four clamps grip under the rail lip, with eight slots so the clamps can land where your bed allows. A plastic drop-in liner may need trimming or drilling, and if you choose through-bolts or J-bolts in an aluminum bed, coat the holes with zinc-rich primer (not included).
What changes between steel and aluminum?
Gauge and weight. Weather Guard lists 18-ga bodies for the steel boxes and 15-ga for aluminum; in the 72" extra-wide size the steel 116 weighs 163 lb and the aluminum 117 weighs 97 lb.
Why won't the lid latch yet?
Weather Guard notes the lid may not latch properly until the box is clamped down at all four points, so finish the mounting before you judge the latch.
Installation

TypeCrossover mount on top of both bed railsfour clamps grip under the rail lip (Weather Guard sheet 24-00155)
Tools1/2" ratchet wrench and a ruler
Here's the short version. Follow Weather Guard's install sheet (below) for the exact positions and hardware.
- Code the locks with the supplied keys before first use. Once a lock is coded it cannot be changed, so decide whether all your boxes share one key.
- With the truck parked on level ground, set the box on the bed rails and center it with a ruler. Check the cover opens fully without hitting the cab.
- Fit a mounting clamp, carriage bolt and fender washer in four of the eight slots, starting at the driver-side front and working clockwise.
- The cover may not latch until all four clamps are tight, so finish bolting before you test it.
- On an aluminum bed, use the aluminum upfit parts. Prime any drilled holes with zinc-rich primer.
- Check the clamps for tightness from time to time.

Great brand. Very sturdy. This one is very deep, yet has slim cover that allows clear rear view to driver.
