Designed for use where the depth of a deep throat or the extreme strength of a heavy duty pattern are not required. Forcing screw has a square head and a sliding handle with standard V threads. Swivel pad completely encircles the ball joint providing permanent attachment as well as full swivel action. Heavy walled hub supports forcing screw reducing distortion. Extra large anvil for greater gripping area. Anvil is produced to insure a flat surface for proper alignment with screw. Made in the USA.
