Gripple Seismic Bracing Systems are ideal for use on nonstructural components and equipment requiring seismic design, such as in essential facilities that are required for emergency operations in the aftermath of an earthquake. 4 Way Bracing Transverse Bracing Longitudinal Bracing Important Information GRIPPLE SEISMIC restraint bracing systems should only be used in conjunction with threaded rod at required seismic bracing points. NEVER EXCEED THE MAXIMUM LOAD OF THE PRODUCT. During installation take slack out of assembly by hand pulling the tail end of the cable. COMPLIANCE WITH LOCAL CODES and, where applicable, NATIONAL CODES are the buyer s and / or installer s responsibility. INTEGRITY OF THE BUILDING STRUCTURE to which Gripple Seismic Bracing Systems are attached is the responsibility of the installer and / or specifying engineer. DO NOT APPLY LUBRICANT to any part of the assembly. DO NOT USE FOR HOISTING such as in a crane or pulley situation.
