Schaefer Stand-Up Blocks

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