This is the Forester brand Full Chisel chainsaw chain loop for a 20" bar. This chain is 72 drive links (count both cutters and non-cutters). This chain is 3/8" pitch, .050 gauge. This is NOT safety chain, so the risk of kickback is higher. Please be cautious and comfortable using a saw before you purchase. I advise using all safety protection, chaps, eye protection, hearing protection, and a face sheild. Bottom line: this stuff REALLY cuts fast.
