Use swivel bases when leads must rotate to face the trimmer. Ball bearing swivel bases feature dual rows of Delrin® ball bearings to ensure that they swivel freely even under high loads. The bases include a stop that prevent the base from swiveling completely and fouling lines.

• Use for mainsheets, jib sheets, and control lines
