Description
Overview:
This 25" (63.5 cm) RS chainsaw chain loop is built for heavy-duty cutting on machines that take a .404" (10.3 mm) pitch and .063" (1.6 mm) gauge chain. With 77 drive links, it matches many 25" guide bars designed for .404 x 1.6 mm setups, helping maintain correct bar and sprocket engagement. Made from heat-treated steel with precision-riveted links, it is designed to handle demanding work in forestry, landscaping, and large-scale timber cutting. The chain delivers consistent, accurate cuts when correctly tensioned and sharpened, and is suitable for users who need reliable performance across hardwoods and softwoods. It is compatible with chainsaws that use this specification, including popular older professional models such as the Stihl 041.
