Schaefer M-Series Block M66-05

Single Block. Computer machined block finished in hardcoat anodized black for durability. Torlon(tm) rollers and Delrin(tm) ball bearings ensure a low-friction aluminum sheave that will handle high loads. Machined center of the block may be used as a " becket" eliminating the need for other blocks. Forged D Shackle on a swivel head may be locked in place to eliminate line twist. Flushing holes in each cheek allow easy flushing.
