Oregon Single Rivet bar and chain combo's are a great buy for any homeowner. Single rivet bars are common with woodcutters using electric or small gasoline-powered chainsaws and pole pruners. Small radius nose helps reduce kickback. The slim symmetrical contour is light in weight, maneuverable, and reversible for added life. Oregon Single Rivet chainsaw bars only run 3/8" pitch low profile chainsaw chain and we paired this one up with Oregon's 91PX chain. This chain has guard links on the tie straps, so it is ANSI approved as a low kickback chain. This makes 91PX an excellent choice for casual users.
