Weather Guard was founded as a small sheet-metal truck-box line in St. Louis, Missouri, and was acquired in 1968 by Knaack LLC (now part of WernerCo). For nearly 60 years, Weather Guard has built a reputation for making some of the safest, most durable truck boxes and van storage equipment on the market. For HVAC contractors running pickup-based service rigs, Weather Guard is the default pick for crossover tool boxes, saddle boxes, low-side boxes, and Defender Series weapon-storage-rated boxes, all designed to survive years of weather, corrosion, and break-in attempts.
On the van side, Weather Guard offers a full lineup of cargo-van shelving packages, drawer units, bulkhead partitions, and ladder racks for Transit, Sprinter, ProMaster, and Express/Savana chassis. The Pack Rat drawer unit is a staple in HVAC service vans for organizing screws, fittings, and small parts. The company's welded-steel construction, powder-coat finish, and patented locking systems are tuned for the same contractor-abuse environment that Knaack built its reputation on, and the two brands share distribution, accessories, and parts systems.
Sold through WernerCo's network of contractor-supply distributors, big-box retailers (Home Depot, Lowe's, Tractor Supply), and upfitter dealers, Weather Guard is one of the easiest truck-equipment brands to source and service nationwide. For HVAC shops standardizing a mixed fleet of pickups and vans, Weather Guard plus Knaack gives you a single unified vendor for jobsite, truck, and van storage with interchangeable accessories.
