"Avoid downtime and keep your project running."


We offer 3 specific grades of grouser bars; High CarbonHeat treated, and Chrom-X, all designed to meet your Ice lugging requirements. 


R.F Butler premium bar is always hot rolled then cut or sheared to length. Many competitors lugs are cast or forged which creates excessive porosity and inconsistent hardness levels throughout the lug. These two factors greatly increase the probability of premature failure.


Ice lugging your machines with RF Butler lugs will increase machine efficiency and productivity by maintaining machine traction / stability on ice, snow, muddy or highly sloped conditions. All profiles and grades can be cut to any length on request. For your convenience, we also stock pre-cut ice lugs in a variety of the most popular sizes.
