Adjustable Spacer Design
Optional hole mounting positions and reversible hub features allow adjustment to accommodate most shaft spacing requirements (see Page E-8). 		Universal Hubs
Straight bore and compression bushed hub designs are identical and interchangeable for both the spacer and standard couplings. This means maximum utilization of off the shelf inventory.
