About Pulleys

Hanging Pulleys for Rope—For Horizontal Pulling
Hang these pulleys from hooks, screws, and bolts to assist with horizontal pulling or to guide a rope.
Pulleys with two grooves are for use where multiple pulleys move a single load, such as block and tackle systems. They require about half the force of a single-groove pulley to move the same load.
Pulleys with a bearing are easier to turn than pulleys without a bearing.
Acetal, nylon, and aluminum are lightweight and corrosion resistant. Stainless steel is the most corrosion resistant.
Styles C and H have a bracket on the bottom for tying off one end of a rope.
Style J reduce the force needed to hold your load in place. Unlike standard pulleys, these have a V-groove for more grip on your rope, and they ratchet when under load so they won't slip in the other direction. Pulley for 3/8" dia. rope can be set to ratchet even when not under load.

Easy-Open Hanging Pulleys for Rope—For Horizontal Pulling
Also known as snatch blocks, these pulleys open so it's easier to feed the rope through the housing—a free rope end is not needed. Use them to assist with horizontal pulling or to guide a rope.
Pulleys with a bearing are easier to turn than pulleys without a bearing.
Aluminum is more lightweight than stainless steel. Stainless steel is more corrosion resistant than aluminum.

Machinable Pulleys
Customize the groove and bore to fit your application. The center of the pulley has a pilot hole so you can drill a bore to match a specific shaft size. Nylon is easy to machine yet resists impact and corrosion.

Hanging Pulleys for Rope—For Lifting
Hang these pulleys from hooks, screws, and bolts.
Pulleys with two grooves are used in applications where multiple pulleys move a single load, such as block and tackle systems. They can reduce the force needed to move the load by up to two times compared to single-groove pulleys.
Pulleys with a bearing are easier to turn than pulleys without a bearing.
Style A pulleys have a bracket on the bottom for tying off one end of a rope.
Warning: Never use to lift people or items over people.
