K Series (Heat Resistant Series)
The U.S. Tsubaki "K" series is made of a resilient new engineering plastic which can withstand environments where temperatures reach 284°F. In contrast to plastic chains made of conventional plastic, this chain will not lose its valuable properties at high temperatures.
K Series chain is clip-type construction and has a slightly longer pin.
