SKU: 90SG039CK Category:


90SG039CK 3/8″ pitch, .043 gauge 39 Drive Links

Oregon® Micro-Lite™ 90SG is made for small saws and features a chamfer-chisel cutter design that outcuts

competitive chains. 90SG cuts a narrow kerf, requiring less power from the saw than standard chains

to make the same cut. Micro-Liteâ„¢ 90SG is a low-vibration/low-kickback chain which meets both the ANSI

(U.S.) and CSA (Canadian) low-kickback requirements. This chain is ideal for homeowners or consumer

users, and is equally well suited for commercial cutters such as arborists and orchardists. Micro-Liteâ„¢

90SG is designed for use on electric saws with bars up to 16 inches (41cm), and on small gasoline-powered

saws up to 2.5 cubic inches (41cc) with bars up to 14 inches (35cm). 90SG is compatible with all existing

91-type drive sprockets, and its narrow .043-inch gauge requires the use of a Micro-Liteâ„¢ bar.
