Hanging Pulleys for Rope—For Horizontal Pulling


Style A	Style B	Style C	Style D	Style E	Style F

Style G	Style H	Style J	Style K	Style L	Style M

Style N	Style Q	Style R

Hang these pulleys from hooks, screws, and bolts to assist with horizontal pulling or to guide a rope.

2 Grooves—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.

Roller Bearing—Pulleys with a bearing are easier to turn than pulleys without a bearing.

Styles C and H—Styles C and H have a bracket on the bottom for tying off one end of a rope

Style J—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.

Aluminum and Acetal—Acetal and aluminum are lightweight and corrosion resistant.

Nylon Housing—Nylon is lightweight and corrosion resistant.

Easy-Open Hanging Pulleys for Rope—For Horizontal Pulling


Aluminum	Stainless Steel

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.

Needle Roller Bearing—Pulleys with a bearing are easier to turn than pulleys without a bearing.

Aluminum—Aluminum is more lightweight than stainless steel.

Stainless Steel—Stainless steel is more corrosion resistant than aluminum.

Hanging Pulleys for Rope—For Lifting


Style A	Style B	Style C

Hang these pulleys from hooks, screws, and bolts.

Warning: Never use to lift people or items over people.

2 Grooves—Pulleys with two grooves are for use 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.

Roller Bearing—Pulleys with a bearing are easier to turn than pulleys without a bearing.

Style A—Style A pulleys have a bracket on the bottom for tying off one end of a rope.
