Lamination Wrists for Passive & Mechanical Hands
These lightweight nylon wrists are often preferred for passive hands if no wrist motion is required. If wrist pro/supination is required, use a Light-Weight Friction Wrist with a ½-20 stud plate.
Passive hands are supplied with round wrists so that they can be readily interchanged with other round-wrist terminal devices. When fitting just a passive hand, use an oval wrist. Four screws remove the round insert from the hand exposing the attachment for the oval wrist. The foam is then reduced to match the nylon wrist piece plus the thickness of the laminate. The dimensions given below are the nominal measurements over the laminations. The actual diameters are about 1/8" smaller.
