Schaefer Single Stainless Steel Block with removable becket enables pre-spliced lines to be easily attached.
Universal head allows one block to function as a front shackle, side shackle, or swivel shackle block. Large sheave diameter and high working loads make them suitable for sheet and control blocks on medium to large offshore boats. Beckets are removable. 704 series are aluminum; 705 blocks are stainless. Where applicable, blocks use 1/4" fasteners.
