CMC ProSwivel Single and Double Pulleys 1.5

SKU 300430,300431,300432 Categories ,


Both single and double pulleys include a built-in swivel and rotating sideplate.


The CMC ProSwivel Pulleys combine a swivel and pulley into one tool with a unique sideplate that opens while the pulley is still attached to the anchor. Teaming up with Rock Exotica, CMC now offers more swivel pulleys certified to NFPA standards. Our renamed and expanded ProSwivel line includes eight pulleys to choose from. You can pick the best CMC ProSwivel Pulley for the job, going bigger when you need more efficiency.

Expanding on the original, patented swivel pulley line by Rock Exotica, the CMC ProSwivel Pulleys are time-tested, Made in the USA, and brought to you by two companies committed to quality and service. Available in single and double sheave versions from 1.1″ radius up to 2.6″, these pulleys are an excellent option for Mechanical Advantage (MA) systems for hauling and ascending, and they work well in combination with high anchors, tripods, and redirects.
