FEATURES AND BENEFITS
CHAIN
58- AND 59-SERIES SQUARE-GROUND CHAINS
These new Oregon® .404”-pitch Super Guard® chains have been carefully developed to replace the
popular 52AJ/AK/AL family of square-ground chains. Users of our previous 52-series chains will find it
easy to make the switch. 58CJ/CL, and 59CJ/CK/CL all feature a fast-working new chisel cutter that
delivers performance superior to its predecessors in all cutting modes. The new cutter is mounted on
our proven unequal-pitch 59 chassis for superior performance and durability. These chains give
professional timber cutters who use square-ground .404”-pitch chains what they want: out-of-box
sharpness, the ultimate in performance, resistance to stretch, and consistency from chain to chain.
These chains feature ramped depth gauges to reduce kickback energies, and are recommended for
cutting clean wood with saws 4.0 cubic inches (65cc) and larger, and with bars 20" (50cm) and longer.
Safety/ANSI: 58CJ/CL and 59CJ/CK/CL are yellow-label chains with kickback-reducing
features. These chains do not meet the kickback requirements for low-kickback chains.
Recommended Use: Professional use by loggers and forest firefighters who prefer
large saws and square-ground .404”-pitch chain.
