The wear strip was developed to eliminate seed leakage from between the canola disk and meter housing.  

Additional benefits include less wear on the canola disk itself as it won’t be rubbing directly on the metal meter housing, but on the plastic wear strip and additional adjustment on the seed disk itself, especially evident on already-worn meter housings. One of the biggest challenges with planting canola has always been seed leaking from between the disk and meter housing. The way to prevent leaking is to tension the disk against the meter housing, which in turn causes wear on the meter housing. With the RRV wear strip, you stop wearing out your metal meter housing and wear out the affordable, replaceable wear strip.
