If standard mounting holes are required, specify low shaft rails with pre-drilled mounting holes by part number. For example, LSR-12-PD. Hole sizes and spacings are shown in the table. If other than standard hole spacing is required, please provide drawings with all dimensions, tolerances, and quantity. With or without mounting holes, low shaft rails will be supplied in 48" lengths when ordered by part number.

Precision case hardened and ground shaft, plus an LSR steel support rail, effectively doubles the life of the shaft by allowing it to be turned over for a fresh surface when wear becomes evident. Both sides of the shaft are counterbored so the shaft may be rotated 180°, and rebolted for use on the new side. This guide is sold as a two-piece set; the shaft and support are not assembled. The guide is then bolted down through the top of the shaft
