The Manfrotto 386BC-1 Nano Clamp is a tiny but powerful
black aluminum clamp, able to hold up to 8.8 lbs (4 kg). It weighs only
3.88 oz (110 g) and can grip a round tube with a diameter from 0.5 to
1.37" (13-35mm). It uses high friction tape to improve the grip and has a
pull-and-lock aluminum handle. With 1/4" and 3/8" adapters, it can be
mounted virtually anywhere.
