Throwing Arm for The Louisville Slugger Ultimate Pitching Machine or the UPM 45 .

This is the Steel Throwing arm that throws the ball. Ball is placed on this before the pitching machine power lever is stepped on.

There are two Rubber Runners that go on the Throwing Arm so the ball gets the proper backward spin.
