  • Wider for ease of walking chain back on without removing cover 
  • Field tested to ensure quality

  • Includes captive bar nuts and chain sliders
  • Made in the USA
  • Patent Pending

*Note: Pro Safety 4 and 5 point (461, 460, 046 models only)  felling dogs are not compatible with our clutch cover. 

*If you plan to run a 404 chain, you may need to shave 0.015 (inch) off the chain slider to allow for the additional width.

Installation Tip - Felling dog bolts need to be installed from the inside of the cover, facing out so that the nut is on the outside of the felling dog. After this, put the cover flat on a table and make sure that you pound the chain sliders down until it stops against the cover - as far as it will go. The clearances are super tight so we get maximum wear out of our chain sliders. Once they are down tight your chain will spin freely. 

This cover is not offered with captive bar nuts. We found through testing that a traditional style cover proved stronger. In addition, captive bar nuts require special tooling to replace.
