Stainless Steel Seine Block with Hook 4

These are solid and strong blocks! Not meant for saving weight, meant for strength! Solid stainless steel sheave, cheek & swivel. They have a spring loaded "gate" so that the line can be easily inserted (like a snatch block) and it wouldn't pop out. Removable pin & sheave, brass bushings. W denotes wire rope sheave, all others fiberous rope sheaves. Suncor. A = Rope. B = Eye. C = Length.
