Product Description

Available while supplies last.

Micro-Lite™ .043" Gauge Saw Chain

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-Lite™ 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-Lite™ 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-Lite™ bar (not included).
