Concept2 oarlocks come with replaceable bushings for pitch adjustment and pin fit. Different colored bushings fit different pin diameters as shown in the table below.
| Bushing Color | Sweep | Scull |
|---|---|---|
| Black | 9/16" | 1/2" (and adapter*) |
| Blue | 13 mm | 13 mm |
| White | 1/2" | 7/16" |
| * Note: Adapter for “crescent” type scull backstand fits into black 1/2” scull bushing. | ||
Adjust oarlock pitch from 1 to 7 degrees by selecting two bushings with the desired pitch (pitch is imprinted on the bushing) and inserting them in opposite directions as shown in the drawing. (If replacing existing oarlocks, keep in mind that most non-adjustable oarlocks have a built-in pitch of 4 degrees.)
