The Harken 6235 is a 45 mm aluminum Element fiddle block featuring an integrated Harken 150 cam cleat and a swivel/locking shackle — a versatile, high-performance sailing block engineered for mainsheet, vang, and other high-load control line applications.

The sideplates are crafted from forged aluminum shaped into compound curves, providing exceptional structural strength while minimizing unnecessary material.
