The reversible claw legs can either sit on the outside or on the inside of a part that is going to be removed. The legs can be adjusted to fit correctly around the edges of the part.
The forcing screw can be removed from the cross arms and placed the other way around to enable the legs to swap from internal to external use.
The forcing screw sits against the centre of the shaft. It pushes against a shaft or casing while the legs pull and remove the part.
The hexagonal head allows use with a spanner or a socket wrench.
