VMC Group SCR Seismic Cable Restraint Kit is a seismic cable kit used to seismically restrain isolated, suspended piping, ductwork, electrical services and various suspended equipment.  

The SCR Seismic cable kit comes in two alternative configurations. The  SB-125 Kit for 1/8" seismic cable, the SB-250 Kit for 1/4" seismic cable, and the SCR cable kit for 3/8" cable. The SCR Kits come with two single hole brackets for attachment to structure and two slotted brackets for attaching to piping/equipment supports. All SB brackets come with nuts and bolts pre-attached to the bracket for attachment of cable to the bracket. Each kit comes with 11' or 20' of pre-cut cable lengths or various length rolls of cable. The SCR Seismic Cable Kit for 3/8" seismic cable come with two heavy-duty seismic brackets for attachment to the structure, two seismic brackets for attachment to the piping supports, swaged cable with one end terminated with thimble and crimp, U-bolts, thimbles and shackles. Each kit comes with either 11' or 20' of pre-cut cable lengths or various length rolls of cable. VMC seismic cable restraints are positioned at a 45° angle from the point of support. The diameter of the cable is based on the weight of the equipment and specified seismic force.

VMC seismic cable restraints ensure positive attachment to the structure and distribution systems. When installed slightly slack, they do not compromise the vibration isolation by short-circuiting the isolation hanger.
