Sur-Lock® Liner Retention System


Designed to drastically reduce the amount of time it takes to change a liner, the Sur-Lock® Liner Retainer eliminates the need for hammers to generate the necessary torque required by integrating a torque multiplying pinion and bull gear into a conventional liner retention system. We also reduced the weight of our liner nut to make change-outs safer and easier. The time to install a liner and tighten to the required torque is reduced to 45 seconds.
