Schaefer Single Aluminum Block includes an integral becket that allows either a 2:1 or 3:1 purchase.
Universal head allows one block to function as a front shackle, side shackle, or swivel shackle block. Large sheave diameters 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.
