Beaver_stortThis is a traction chain for forestry, construction and snow clearing - excellent traction, smooth riding and virtually trouble free operation! The SMT is manufactured in 11, 13, 16 and 19mm chain.
The photo shows the pattern used on 13 - 16 and 19 mm.  The 11 mm version is designed similar as SMT 8 and 9,5 mm

All SMT-versions have oversized studs to increase grip and strength.

Tightening rail is standard for tire profile 55 and lower, otherwise optional. Separate chain tighteners are advised when installing heavy chains.
