Split Set® Friction Rock Stabilizers - Rock Bolts for Reliable Ground Support
Split Set® friction rock stabilizers are manufactured by International Rollforms, Inc. for underground or
above ground applications in mines, tunnels, slopes, or wherever reliable ground support is needed. Our friction
rock bolts produce superior holding power due to their unique design that exerts pressure against the rock over
its full contact length immediately upon installation. When ground shift occurs, our rock bolts conform to the
changing ground conditions. The result is a tight grip that actually grows stronger with time and ground movements,
providing reliable ground support. It never needs tightening.
Our friction rock stabilizers are a simple system requiring only 2 parts, a tube and bearing plate. Fast, easy
installation takes usually less than a minute - just drill and drive. Split Set® stabilizers come in 3 models.
They are available in lengths and sizes to meet your needs and are made of standard, galvanized, or stainless
steel.
