VMC Group SB-250 Seismic Cable Brackets are for use with 1/4" cable. The bracket is designed so that a 1/4" cable will quickly loop under and around the head of two bolts on the flange for ease of installation.

Seismic brackets are predominantly used with seismic cables in suspended piping, conduit and equipment to provide a tension restraint in the direction of the cable. Typical equipment installations utilize four lengths of cable with each one attached at a corner of the equipment. The cables are splayed at approximately 45° from the equipment.

The SB-250 Brackets meet the highest quality standards. They have been independently tested, rated and are FM Approved for use with strut channel or angles.
