Sinker bars

Sinker bars are used to add weight to cable percussion tools, or to drive casing into the ground. Standard sinker bars are 41/2″ (114.3 mm) in diameter, with an effective length of 40″ (1.0 m) and weigh approximately 80 kg each. The top sinker bar has a strong swivel eye, designed to our own specification, and secured by a tapered nut and pin.
