CABLE BRACING COMPONENTS

Cable Bracing
Suspended piping can be safely prevented from swaying during earthquakes using properly designed restraints. Cable restraints were originally designed for vibration isolated systems since the cables do not interfere with isolator function but effectively control movement. Because of the Mason SCB cable systems' effectiveness and ease of installation, SCB cable restraints have replaced solid restraints as the preferred restraint system.










 MASON SCB - The Mason SCB Brackett was designed to provide a dependable end connection that is easy to install. The Cable restraint bolts are included in hte SCB assembly and additional cable clamps are not required.

MASON SCBH - With the Mason SCBH hooks, seismic bracing can bee attached to the support rod at the top of the clevis. The clevis no longer has to be disassembled to install the restraints, but would need to be disassembled to install the pipe sleeve cross bolt braces.
