The Medium Air-Lock has a diameter of 47 mm. It is the ideal addition to the Air-Lock (57.4 mm) and the Small Air-Lock (31.5 mm), and it allows you to perfectly match the distal diameter of the residual limb. The weigth limit is the same as for the other Air-Locks (120 kg) and it is also waterproof in fresh water.
