Pulley Blocks Pulley Blocks for Wire Rope Pulley blocks, also known as shell blocks, consist of a single, double, or triple pulley enclosed in a housing that has mounting hardware for suspending the block. A rope end is fed through the housing for operation. Most often the mounting hardware is a hook, eye, or shackle (see mounting hardware styles below). However, some units have mounting holes so you can attach your own mounting hardware (this style is also known as a tail block). Pulley-access blocks, also known as snatch blocks, open from the side (see styles below) so it's easier to install the rope—no free rope end is needed. They consist of a single or double pulley enclosed in a housing that has mounting hardware for suspending the block. Most often the mounting hardware is a hook, eye, or shackle (see mounting hardware styles below). Some units also include a tie-off bracket (also known as a becket) mounted to the housing for easier set up in multiple-block applications. Steel— The strongest pulley blocks we offer. Zinc-plated and galvanized steel are corrosion resistant. Heavy duty steel are heavier gauge to withstand the most demanding conditions. Stainless Steel— Offer superior corrosion resistance. Bearings— Plain bronze bearings are long lasting for use in slower moving applications. Roller bearings spin freely without resistance. Ball bearings have less friction, making them ideal for faster applications and quick direction changes. Plain bore pulleys ride directly on the shaft.
