For large size drawings, blueprints, artwork, or sketches blueprints hanging clamps are an excellent method for keeping your projects organized and accessible. Made from lightweight extruded aluminum these clamps can hold up to 100 drawings per clamp. We offer options that include clear plastic label holders (labels included) for keeping multiple document projects together and organized for easy access in the future. These hanging clamps also work great as just a binder to hold together multiple page plans for easy page turning and allowing page additions without needing staples to hold the pages together. A set of plans can still be rolled with a hanging clamp for on the job transportation and usage. Engineering Tools offers blueprints storage racks (hanging file centers) that will work with these hanging clamps for storing multiple sets of projects for a clean and organized look.
