The Nano Jug is the smallest jug within the Bleaustone Series. Having the smallest footprint of all jugs, yet still having high positivity.
Because of the small footprint they can be put on poorly designed resin climbing walls. Each hold is designed with anti-rotation in mind; Ensuring the hold's footprint is big enough so the maximum moment that can be applied is less than the force required to rotate the hold -by having sufficient friction beneath it. They also have a screw hole to secure them should you wish to do so.
