Schaefer Line Lead Block – Half-Moon, Hinged Base, Aluminum Sheave

Schaefer offers several ways to bring your halyards and control lines back to the cockpit. Our Halyard lead blocks feature our M-Series design with aluminum sheaves for a strong yet light lead. Fixed and hinged lead blocks feature delrin ball bearing sheaves with stainless steel cheeks for a strong yet smooth lead. Half-Moon mast base blocks feature aluminum sheaves running on nomex/Teflon bearings for smooth running and exceptional static load strength. As always, consult us with any questions.
