ISOTECH® Rigid Restraint System IRRA-3000R is an OPM approved seismic restraint system designed for suspended distribution systems and equipment. It provides maximum lateral load protection of up to 3000 lbs when attached to a steel structure. Engineered with high-strength steel, the IRRA-3000R Rigid Restraint Kit includes two IRRA-3000R bracket assemblies, four ½” Grade 5 bolts, and four ½” strut channel clamping nuts.
ISOTECH’s strut clamping nuts feature teeth that grip the channel’s in-turned edges, forming a “box” configuration for increased strength. Each ½” clamping nut offers a maximum allowable pullout strength of 3000 lbs and slip resistance when installed on 12-gauge solid strut channels.
The IRRA-3000R brackets, hardware, and clamping nuts come with an electro-galvanized finish for corrosion protection, ensuring long-lasting durability in demanding environments. This system is compatible with various anchor types, though the anchors, strut channel, and connections to building structures are supplied separately.
Ideal for seismic applications, the IRRA-3000R is your go-to solution for securing heavy suspended systems, ensuring compliance, safety, and optimal performance.
