CRYSTAL LAKE, IL – Knaack LLC’s new WEATHER GUARD Hi-Side Truck Boxes provide contractors with secure, durable, and convenient tool storage above the bed of their trucks. Available in aluminum and steel, the Hi-Side truck boxes have been specifically designed for extra security and durability with a new three-point latching system that secures each side of the box with a strong seal against theft, vandalism, and weather. A large, stainless-steel D-handle allows for easy opening and locking.

The Hi-Side boxes’ picture frame body design has an extra large opening for maximum utilization of storage space and tool accessibility. Sturdy, adjustable legs allow the box mounting points to be customized for maximum bed space.

For unrestricted access, the doors of the Hi-Side truck boxes can be adjusted from 90 to 180 degrees. Full weather stripping and close tolerance door flanges keep rain, sleet, snow and vandals away from the truck box contents. Full-length staked piano hinges on the doors provide maximum durability and rigidity, and aircraft-rated type cables connect the doors to the full-length reinforcement channel on the truck box body.

Available in 16 aluminum models and 11 steel models, there is a Hi-Side truck box designed to fit all full and compact pickups. Hi-Side truck boxes can also be used on flat bed trucks. WEATHER GUARD Hi-Side truck boxes range in capacity from 5.6 cubic feet to 21.4 cubic feet. For contractors needing additional storage area, Super-Side truck boxes provide extra storage capacity.

The aluminum Hi-Side truck boxes are constructed of heavy-gauge diamond plate aluminum and come in a choice of Clear or Black ARMOR-TUF powder coat finish to maintain a new appearance for years. The steel models are constructed of heavy-gauge steel with aluminum doors and reinforcing channels. The steel models are available in either Brite White or Black ARMOR-TUF powder coat finishes.

The Hi-Side truck boxes come with a three-year warranty. Visit www.weatherguard.com or call (800) 456-7865 to find the nearest distributor.
