Pixel chain: Pixel chains and guide bars, with narrow chassis, provide a narrow cut, low weight and enhanced cutting efficiency. Low kickback: Guarded drive link (G) means less prone to kickback and easier to handle. Golden tie strap for easy filing: A golden-coloured tie strap makes it easy to spot where to start and stop filing the chain. Sharp out of the box: X-CUT chains come carefully sharpened, so you will be ready to cut immediately. The outstanding grinding process provides razor-sharp edges, precise cuts and superior cutting efficiency. Compatible with the Following: 435, 440, 445, 450, 450 Rancher
