Rope Retention Pulley XXL 1/2 to 3/4 in Synthetic Rope (00266)

The Rope Retention Pulley XXL scales the friction pulley idea up to industrial winching, taking 1/2 to 3/4 in synthetic rope with a 56,000 lb WLL at 3:1 or 34,000 lb at 5:1. At 68 oz it is still far lighter than a steel block of the same capacity, and the patented rubber fingers keep heavy rope captured in the groove whenever the line goes slack.

Features

• Industrial size friction pulley for 1/2 to 3/4 in synthetic rope
• Patented rubber retention fingers keep the rope in the groove when the line goes slack
• Multiplies pulling power or redirects the winch line without a heavy snatch block
• Oversized hole radius gives the soft shackle a smooth bearing surface and keeps its legs off the edges
• Critical friction surface is PTFE treated for slickness and heat dissipation
• Machined from billet 6000 series aluminum
• Hard anodized to MIL-A-8625 F
• CE and UKCA compliant
• For synthetic rope only, used with an industrial Standard Duty soft shackle
• Engineered, tested and made in the USA

Specifications

• Rope compatibility: synthetic rope 1/2 to 3/4 in (12 to 19 mm)
• Working load limit: 56,000 lb at a 3:1 safety factor
• Working load limit: 34,000 lb at a 5:1 safety factor
• Finish: hard anodized
• Material: billet 6000 series aluminum
• Weight: 68 oz (1,928 g)

A friction pulley does lose some efficiency, roughly 10 to 20 percent depending on load, so it will not match a bearing snatch block for pure mechanical advantage. What you get instead is a pulley you can rig in seconds, with no pinch points for fingers, that keeps the rope captured in the groove when the line goes slack, and weighs a fraction of a steel block.
