Compare standard, hanging, and mounted pulleys, then calculate the capacity you need based on the angle of your rope.
Hanging Pulleys for Rope—For Horizontal Pulling
 |  |  |  |
Style M | Style N | Style Q |
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.

Style 4 |
|
 |
Mount these pulleys to a flat surface.
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.
