Description

Like the 5 Series blocks, but with Schaefer’s ball-bearing sheave. Curved ball races allow Schaefer ball-bearing blocks to take higher loads than other similarly sized blocks.

Schaefer offers several ways to bring your halyards and control lines back to the cockpit. Fairlead blocks feature our M-Series design with aluminum sheaves for a strong yet light lead. Fixed lead blocks feature Delrin(tm) ball-bearing sheaves with stainless steel cheeks for a strong yet smooth lead. Extremely low profile keeps halyards and control lines close to the deck.
