CMC ProSwivel Pulleys are all certified to NFPA standards. Please note we are currently phasing-in dual certified pulleys that are classified to both NFPA and EN standards. As these parts become available, we will update the product photos and the certification table below. Please contact Customer Support if you have any questions.
CMC ProSwivel Pulleys combine a swivel and pulley into a single device with a moving sideplate that allows rope loading/unloading while attached to the anchor. Available in sheave sizes from 1.1″ radius up to 2.6″, these pulleys are an excellent option for mechanical advantage systems for hauling and ascending, and they work well in combination with high anchors, tripods, and redirects.
Teaming up with Rock Exotica, CMC now offers more swivel pulleys certified to NFPA and EN standards. Our expanded ProSwivel line includes eight pulleys to choose from. Select the best ProSwivel Pulley for the job, going bigger for more efficiency or smaller when weight is critical.
