Wear Runners

SNO-STUFF is the oldest and most experienced manufacturer of high quality wear runners in the industry.  SNO-STUFF also produces a superior quality and designed customer carbide and now SNO-STUFF is producing the best hard-faced wearbar called "Hard Bar" in the industry.  (Good stuff newsletter). 

Hard Bars are made using the same high quality material and forming fixtures as used for our standard wearbar.  The big difference is the unique hard-face weld SNO-STUFF uses.  It actually gets harder as it wears.  The combination of our quality standard bar and the special hard-face material provides for the ultimate in non-carbide wear runners.  (Drag test).

Carbide Runners

Three years of testing and evaluation has enabled SNO-STUFF to produce a superior CARBIDE RUNNER.  The main advantages are: 

1.  LESS  BAR EROSION 
     Grooved only where carbides are located 

2.  TAPERED CARBIDE DESIGN

*Hardbars were advertised, but Sno-Stuff was unable to produce any.  That is why they mention the 1987-1988 season in their 1989 newsletter.

In 1986-87, they claimed...now SNO-STUFF is producing the best hard-faced wearbar, called "Hard Bar," in the industry

And, they also claimed... SNO-STUFF is very proud to have discovered the family secret and be able to provide quality, long wearing hardbars  See: Drag tests
