Description

The Carr Lock® System requires that each fixture plate have one mounting hole designated as the primary reference hole (Primary Liner Bushing) and one mounting hole designated as the secondary reference hole (Secondary Liner Bushing or Slotted Locator Bushing). All other mounting holes should be drilled clearance holes used for clamping only, not locating, .015-.030″ over nominal size. Primary Liner Bushings have a tight ID (+.0002/+.0007″ tolerance) to provide precise reference in two-axes. Made in USA. Primary Liner Bushings are available for all Carr Lock® Clamp shank diameters, each in a choice of lengths for different top plate thicknesses (both inch and metric): 13mm 16mm 20mm 25mm 30mm 35mm 50mm
