The plan pro is a water resistant carrying case that you can attach art,blueprints,or other documents to. You can then retract them inside to keep them safe from the elements while they are being transported. Our company views many sets of blueprint on a daily basis and have began developing this device to make viewing and storage more efficient.When typically viewing plans on a job site I would have to fumble though the many sets of plans that I have rolled up in the cab of my truck. Once I had found the plan, I would have to then pull the rubber band off of it (loosing it most times) and on a windy day, have an employee help hold down the corners of the plans while I grab the scale rule from the truck to get my measurements.When finished viewing the plans I would then try to find the rubber band,roll up the plans and put them and the scale rule back in the truck to keep them from blowing away or being damaged by weather. After that my employee and myself could return to work. With the Plan-Pro finding the plan is made easy with a name tag display on the outside of the holder. When displaying the plans you need no assistants . The Plan-Pro fastens to your metal hood or tailgate by scratch proof magnets. It can also be hung on metal studs or a wall with built in hangers. Once in place pull the handle to display the plans.The Plan-Pro has a built in scale rule so no need to run to the truck and find one. After viewing, replace the scale rule on the top of the Plan-Pro, lift the handle from the hood or tailgate to retract the plans and  return to work. The Plan-Pro will not be blown from the metal surface by wind or harmed by a light rain shower and will be right there when you need it for your next viewing. The Plan-Pro is recorded with the US Patent and Trademark Office #US 7931165 B2.    Thank You for veiwing!
