VMC Group offers three types of Rod Stiffeners, Snap-Brace, SRBC and RSC. The SRBC and the RSC Series are seismic rod bracing clamps used as additional support for bracing threaded rods used to suspend piping, ducts, conduit and various other suspended equipment. The Snap-Brace is a unique rod stiffener in that no tools are required to install it. The Snap-Brace uses a standard 1-5/8" strut channel to stiffen the hanger rod against buckling. As its name implies, you just "Snap" it into the strut and it becomes a "Brace" for your hanger rod.

Seismic forces act in all directions. Threaded rods are sized purely for gravity loads, making it necessary to add additional rod bracing to prevent buckling of the rods. Uplift forces can easily exceed the dead load on the rod - resulting in compressive forces. If not braced, the rod can buckle and fail. With the addition of the VMC SRBC or RSC Series bracing clamps, angle steel or Unistrut®/Kindorf® bracing can be quickly and easily added to the rod.

The SRBC is available in two sizes. SRBC 1.25 for a maximum hanger rod size of 5/8" and SRBC 1.50 for a maximum hanger rod size of 1 1/8". The SRBC is used in conjunction with angle iron. The RSC is available in two sizes. The RSC-1 for a maximum hanger rod size of 7/8" and the RSC-2 for a maximum hanger rod size of 1 1/4". The RSC is used in conjunction with Unistrut®/Kindorf® bracing. Currently, the Snap-Brace is available for 3/8" threaded rod.
