Built from carbon steel, it handles a load capacity of 550 pounds and accepts flange thicknesses up to 3\/4 inches with a 5\/8 inch rod size. The integrated locknut prevents loosening under vibration and dynamic loads. This hardware is a standard component in suspended pipe and conduit support systems and is commonly installed by licensed mechanical contractors, plumbers, and HVAC technicians working on overhead support assemblies. It weighs 0.58 pounds and ships as a single unit.\u003c\/p\u003e\u003cp\u003eThis clamp is suited for use in both residential and commercial construction where threaded rod hanger systems are required. It attaches to beam flanges, structural steel, and similar mounting surfaces. Typical applications include suspended pipe hangers, conduit support runs, duct support systems, and mechanical equipment supports. The 5\/8 inch rod size corresponds to standard threaded rod used in most commercial hanger assemblies. Its carbon steel construction provides the strength required for sustained overhead load-bearing service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLoad capacity of 550 pounds for reliable overhead support applications\u003c\/li\u003e\n\u003cli\u003eAccepts flange thicknesses up to 3\/4 inches for compatibility with common structural steel\u003c\/li\u003e\n\u003cli\u003e5\/8 inch rod size fits standard commercial threaded rod hanger systems\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction provides high tensile strength and durability\u003c\/li\u003e\n\u003cli\u003eIntegrated locknut design resists loosening from vibration and movement\u003c\/li\u003e\n\u003cli\u003ecULus Listed, FM Approved, and meets MSS SP-69 Type 23, SP-58, and UL-U.L.C. standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style replacement or new-installation component for threaded rod hanger systems using 5\/8 inch rod and structural flanges up to 3\/4 inches thick, consistent with MSS SP-69 Type 23 and SP-58 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed mechanical contractor, plumber, or HVAC technician in accordance with applicable building and mechanical codes.
