Weather Guard uses 16-gauge steel for durability, security and accident protection. Their bulkheads are powder-coated white to keep the interior of your van brighter. In the last year, Weather Guard reduced the number of models to make choices simpler, installation faster, and instruction sheets easier to follow. Even the Dog Hatch™ door for long length material is made big enough for ease of use, but too small for an intruder to gain access.
