Protecting documents on the jobsite is not only important but many times required to be in compliance with regulations. Engineering tools offers a large range of options for protecting important documents and blueprints such as permit holders and blueprint/drawing lock boxes. Many building and grading contractors, architects, and realtors utilize these rain proof jobsite boxes to protect important documentation. We offer permit boxes with windows and locks as well as commercial size permit boxes that are large enough to safely store your plans and other important documents. These boxes are most commonly referred to as job site boxes, water proof boxes, bulletin boards, permit protectors, construction permit boxes, and weather proof permit boxes. All of our quality outdoor document protection devices are reusable from one jobsite to the next.
