These little suction cups are perfect for building my own set of Soldering Helping Hands. I took 1/8" anchor wire from a local hobby store, cut it into 6" lengths, and then installed these clamps on the end. I then drilled some 1/8 inch holes in a piece of wood and attached the other end of the wire to it. , Perfectly adjustable helping hands Try each clip before you use it.
