Hanging Clamps

Blueprint drawing clamps are a required companion for most blueprint stands. Clamps are made of aluminum and are simple to operate. Insert your drawings or maps inside the clamps jaws and tighten both of the two wing knobs to tighten the clamp. Then simply insert your clamp into the blueprint racks hanger. A hanger is what holds each clamp. So, if a stand has 12 hangers, that means it uses 12 clamps. With a wing knob on each end you simply loosen and the clamps jaws open up to release your drawings or maps when you're ready to take the drawings out. Most people lay the drawings while still held in a clamp out on a reference table or desk and work that way as the clamp acts sort of like a binder for a set of blueprints. Keep in mind that each clamp will hold about 100 drawings that are 20 lb paper each. Drawing clamps are very handy to have. When deciding on which size (length) of clamp you want to buy, go with the length that will hold your drawing. If your drawings have 24" on the short side, then buy the 24" clamps. The 30" and 36" clamps are the most popular as they are the most versatile. For example, a 30" clamp will hold a 24" side of a drawing although you'll have more clamp than you need. Hanging clamps are sold 6 clamps per carton. The brand names of Brookside, Premium Brand, Safco, Alvin, and Mayline are all considered the best in blueprint storage.
