The POWER+ 16" Chain Saw Guide Bar is the only bar we recommended for use with the EGO POWER+ 16-inch Chain Saw (CS1600 models). The 16" guide bar provides effortlessly smooth cuts and features a low kickback design for safety. It is recommended that the bar should be replaced after the second chain replacement. EGO parts are designed specifically for your EGO POWER+ products and offer the highest quality, performance, and value.
