A free floating rim produces the best cutting action in a smooth continuous flow.
The rim wall supports the chain, greatly diminishing the wear and stress on the chain.
The rim is produced with wear depth indicators on the outer edge. When the rim wear reaches the depth of the indicator, it is easy to see that it is time to replace the rim.
Available for 1/4”, .325”-3/8” and .404” pitch for the OREGON® PowerMate drum in either “small” or “standard” inside diameter.
