WARNING! – Pulley Recall

ProSwivel_Pulley_Lineup-1024x358omni-sizes-graphicInspect all CMC ProSwivel or Rock Exotica Omni-Block swivel pulleys immediately.

CMC and Rock Exotica, who makes CMC's ProSwivel pulleys, have both issued recall notices on their 1.1" swivel pulleys and SwivaBiner pulleys. The concern is surrounding the set screws that hold the button in. The button secures the side plate, so if the button comes out, the side plate could open and let the rope fall out - which could mean severe injury or death.

The recall only applies to the 1.1" versions manufactured from February 2020 through October 2022, however both manufacturers are recommending that all of these swivel pulleys be inspected.


If you have a pulley subject to the recall, return it to the manufacturer at no charge for inspection/repair. If you purchased your pulleys from Roco, we will be happy to assist you with the recall and inspection.

If you have 1.1" pulleys made outside of the recall window, or have other sizes of any date, you may inspect them yourself or return them for professional inspection.

  1. 2018 to present
    1. There should be a dab of epoxy sealant that fills the set screw hole. It may be brownish/yellowish or a white/grey color.
    2. If the epoxy is missing, return the pulley for repair.
    3. If the sealant is protruding above the surface, determine the color. If it is white/grey, that's okay. If it is brownish/yellowish, return the pulley for repair.
  2. 2016 and 2017
    1. There should be a dab of epoxy sealant like the current models have, but it will only be white/grey. It's okay if it is above the surface of the hole, but if it's missing, return the pulley for repair.
  3. Prior to 2016
    1. No visible sealant was used on these models, so don't worry when you see the bare set screw. Just make sure the set screw is even with or below the surface.
    2. If you are not comfortable doing this inspection yourself, you can send your pulleys to the manufacturer or to Roco for inspection.
    3. You may want to add your own epoxy to these models to make your daily gear inspections easier. (see details in the inspection notices linked below)

Instructions for identifying your pulleys and locating the serial numbers are included in the manufacturer recall and safety notices. Be sure that you are using the proper notice for your pulley, as the CMC and Rock Exotica serial number locations are slightly different.
