Overview

Handle lines at the mast base with the Harken 80mm Single Element Block with Swivel. For sailors selecting mastbase hardware, it pairs a journal bearing with curved, forged-aluminum sideplates that protect the sheave.

Key features

  • Forged aluminum sideplates use compound curves to add strength.
  • The sideplate layout limits the amount of metal needed to protect the sheave.
