Built to UNC coarse thread standards at 7\/8 inch diameter, this coupler provides a rated safe working load of 10,000 pounds. The design includes witness holes that allow installers to visually confirm both rods are fully threaded into the coupler before applying load. This part is used by electricians, plumbers, HVAC technicians, and general contractors wherever threaded rod hangers or support assemblies require extension or connection.\u003c\/p\u003e\u003cp\u003eThis coupler is suited for interior and exterior applications, making it appropriate for exposed structural environments as well as conditioned spaces. Typical use cases include suspended pipe hangers, equipment support rods, electrical conduit strut systems, and mechanical room support assemblies. Each package contains 5 couplers, allowing a technician to complete multiple connection points from a single unit of purchase. The zinc construction provides adequate corrosion resistance for most standard commercial and residential installation environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8 inch UNC coarse thread for compatibility with standard threaded rod stock\u003c\/li\u003e\n\u003cli\u003eRated safe working load of 10,000 pounds per coupler\u003c\/li\u003e\n\u003cli\u003eWitness holes allow visual confirmation that both rods are fully seated\u003c\/li\u003e\n\u003cli\u003eZinc construction suitable for interior and exterior use\u003c\/li\u003e\n\u003cli\u003eSold in a 5-pack quantity per package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fitment coupler for 7\/8 inch UNC coarse threaded rod used in mechanical, electrical, and plumbing support applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified tradesperson following applicable mechanical or structural codes for the jurisdiction.
