The new aluminum WEATHER GUARD Low-Profile side boxes are now available from Knaack LLC. The new Low-Profile side boxes combine massive storage space with maximum rear-window visibility. The innovative Low-Profile design of the side boxes sits just above the bed rail to keep rear sightlines intact but the extra-wide design allows for the utmost storage space. The new Low-Profile side boxes come with an Extreme Protection™ Lock, protecting each box against break-ins.
