Cylindrical body allows for installation in tight areas. The housing is tapped for backside fastening. The replaceable ball is made from 300 series stainless steel and swivels to allow for self-alignment on uneven surfaces. The flat cone design provides a large contact surface for greater force distribution. A Viton O-ring holds the ball in place while keeping contaminants out and providing smooth ball movement. The housing is made from alloy steel, heat treated to Rc 43/46 with a black oxide finish. Replacement balls and O-rings can be ordered separately.
