Get three lockable drawers of theft-resistant storage in the same compact footprint with the Weather Guard 903-3-01 secure storage module. Splitting the 21" wide cabinet into three drawers instead of two gives you finer organization, separate homes for fasteners, hand tools and small power tools, while a single keyed lock secures the whole stack. Every drawer latches shut on its own and holds even when the cabinet is unlocked, so nothing rattles loose on a rough jobsite road. The welded steel box and drawers resist prying and abuse, and the module mounts to standard 16" deep Weather Guard van shelving and stacks with matching units so your storage grows with the job.
What's Included:
903 Series secure storage three-drawer module in Brite White welded steel
Keyed cam lock with two keys
Three self-latching steel drawers
Mounting hardware for standard 16" deep Weather Guard shelving
Weather Guard installation instructions
Features
Three Drawers for Finer Organization Splitting the cabinet into three self-latching drawers lets you separate fasteners, hand tools and small power tools instead of piling them into one deep drawer. It is the same 21" wide footprint as the two-drawer 902, just divided for tighter organization.
Drawers Stay Shut in Transit Each drawer latches closed and holds even when the cabinet is unlocked, so the three drawers will not slide open on hard stops or washboard roads. One keyed cam lock secures all three at once for overnight peace of mind.
Welded Steel, High-Security Build Welded steel box and drawer bodies plus a heavy-duty locking mechanism give the 903 serious theft resistance on the job and in the parking lot. This is a security-first module, not a light folded-sheet organizer.
Brite White ARMOR TUF Powder Coat The Brite White ARMOR TUF powder coat resists moisture, scuffs and grime and keeps the module looking clean through years of daily van use. The bright finish also helps you spot parts inside a dim cargo area.
Mounts and Stacks Into a System The 903 mounts to standard 16" deep Weather Guard shelving and stacks with other secure storage modules and locking cabinets, so you can combine it with a 902 or add locking cabinets to build one secure storage wall.

Van Shelf Back Panels and Door Accessories Install
Weather Guard's step-by-step guide covers fitting the back panels and door accessories that turn an open van shelf unit into a closed, secure one. Back panels stop small parts dropping down behind the shelving, and the doors keep contents in place and out of sight.
It is the reference to use when you are adding to shelving you already own. Because it is the manufacturer's own video, it shows the correct fixing points and the order the parts go together.
Conquer the Chaos in Your Work Van
Weather Guard's own short film on van storage, built around the difference between a van you have to dig through and one where every item has a home. It shows the Weather Guard van range working as a single interior rather than as separate parts bolted in over time.
It is a useful orientation if you are planning an upfit and are not sure where to start. Because it is manufacturer content, the shelving, bins and flooring shown are the current Weather Guard line rather than an older catalog.
Installation Help for Your Van Accessories
Weather Guard made this video for anyone who would rather not tackle a van upfit alone. It covers the installation support Weather Guard offers on its van accessories and how to get a fitment question answered before it becomes a problem.
Watch it before you start if this is your first upfit. Knowing the support route in advance is usually what keeps a Saturday install from turning into a Monday phone call.

Frequently Asked Questions
Straight answers on specs, fit and support
How many drawers does the 903-3-01 have?
Three self-latching steel drawers in a 21" wide cabinet. It gives you finer organization than the two-drawer 902 in the same footprint, so you can separate fasteners, hand tools and small power tools.
What shelving does it mount to?
It mounts to standard 16" deep Weather Guard van shelving with the included hardware. As a modular unit it attaches to the Weather Guard system, not to the van body, so confirm you have 16" deep shelves and about 21" of open shelf width first.
Will the drawers stay shut on rough roads?
Yes. Each drawer latches closed and holds even when the cabinet is unlocked, so none of the three drawers will fly open on hard stops or washboard roads. The keyed cam lock secures all three drawers at once.
Can I combine it with other modules?
Yes. The 903 stacks with the 902 and other secure storage modules and locking cabinets. Buying a 902 and a 903 together is the same as the 9045 five-drawer kit. Secure the upper unit to the lower one before loading.
How secure and durable is it?
The box and drawers are welded steel with a heavy-duty locking mechanism and keyed cam lock for real theft resistance, and the Brite White ARMOR TUF powder coat protects it against moisture and jobsite grime.
Is there a warranty?
Yes. It is backed by the Weather Guard Limited Lifetime Warranty against defects in materials and workmanship, and it ships at about 46 pounds.
