Buying guide
Where pulleys fit
Swing-side pulleys open to load the rope mid-line, which saves time. Double pulleys build compact haul systems. A downrigger mounts on the trunk to add friction and control for lowering lines from aloft.
Check rated strength and maximum rope diameter for each pulley, and never use a light rescue or haul pulley for heavy, dynamic rigging loads.
Using rigging pulleys well
Larger sheave diameters bend the rope less and keep more of its strength. Pulleys with bearings run more freely than bushings, which matters in haul systems where friction adds up. Double pulleys make 3:1 and 5:1 systems more compact.
Clip pulleys to anchors with rated connectors and slings, and set them so the rope runs cleanly without rubbing side plates. Keep life-support pulleys separate from rigging pulleys, and inspect sheaves for grooves and side plates for bends. Retire a pulley that has been overloaded or dropped.
Common questions
Can I use a climbing pulley for rigging?
Only within its rated load, and keep life-support pulleys separate from rigging gear.
