Bent Arm Pins
Each CHANCE® plated-steel bent arm pin is designed to attach a Kelly bar adapter to a Kelly bar. The pin also is used to secure SS anchors and bumper posts to their drive tools.
Bent arm pins are included with new tools as required. Order replacement pins for existing tools as listed below.
WARNING:
The CHANCE bent arm pin and coil lock are the only tested and approved means for through-pin attachment of drive tools. Do not use any other means of attachment.
Each new Kelly bar adapter or anchor drive tool includes a bent-arm pin with coil lock.
