The Large Oar Right serves as a stop and keeps your blade perfectly positioned in the water for maximum rowing efficiency. Use the Large Oar Right to reinforce an existing stop, or have it work solo. Clamps on using stainless steel bolts. Installs over rope wrap or sleeve. 

The Large Oar Right will fit oars in 2 to 2 1/4 inch diameter ( most whitewater oars )
