The Posi Lock SIDE ALIGN Tool is an all-in-one, go-anywhere portable jack bolt set. Aligning rotating machinery is not just about precision measuring, but also precision moving. Use the smooth power of an eccentric socket to turn rotary motion into controlled linear movement. By rotating the eccentric socket, linear movement is transferred to the machine foot, creating a precise movement to the desired alignment position. If you have precise measuring equipment, SIDE ALIGN provides you with the ability to make precise horizontal adjustments within 0.001 inches or closer. These durable alignment tools add efficiency to an otherwise tedious, meticulous task. Available in standard or metric sizes for machines 2 to 300HP. Kits include carrying case. Individual components also available. The SIDE ALIGN Tool works for machines on studded or tapped bases (not for through bolts).
