For long term storage or project filing Engineering Tools recommends our wide selection of blueprint storage cabinets. We offer 2 drawer metal storage filing cabinets for small to medium size drawings and large vertical storage cabinets for your medium to large sized drawings and blueprints. These cabinets will maintain a dust free clean document that can be secured while you’re away. Gone are the days of the old large flat storage document filing systems; these cabinets offer a more efficient use of space, mobility and security to your important documents. Engineering Tools offers storage clamps that are designed to work in conjunction with the Vertical storage cabinets. The Storage clamps are sold separately and we strongly recommend you look into our Blueprint Storage Clamps for our wide array of options to meet your specific needs.
