What are Shoulder Adapters Used For?

Shoulder Adapters are idle bore adapters with a standoff extending from one side of the center bore. A shoulder adapter is used to extend the shaft laterally past the pulleys bore. This provides space on one side of the pulley. Using a shoulder adapter allows versatility with mounting.
