Built from ductile iron, it delivers a 400 lb load capacity with a maximum flange thickness of 3\/4 inches and accepts 3\/8 inch rod. The locknut provides positive rod engagement to prevent loosening under vibration or dynamic loading. This hardware is a standard component in suspended pipe and equipment hanger assemblies across commercial and industrial construction. It carries cULus, UL-U.L.C., and FM Approved listings, as well as MSS SP-69 and SP-58 compliance, making it suitable for code-required installations.\u003c\/p\u003e\u003cp\u003eThe 23LB0038 is used in suspended hanger systems where a threaded rod must be anchored to a beam flange or structural steel. Typical applications include HVAC duct support, plumbing pipe hangers, and mechanical equipment suspension in commercial and light industrial settings. It is sized for 3\/8 inch threaded rod, which is common in medium-duty hanger runs. The ductile iron construction handles the mechanical stress of loaded hanger assemblies while resisting the impact and vibration common in mechanical rooms and overhead installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400 lb load capacity for reliable medium-duty suspension support\u003c\/li\u003e\n\u003cli\u003e3\/4 inch maximum flange thickness suits standard structural steel beam flanges\u003c\/li\u003e\n\u003cli\u003eAccepts 3\/8 inch threaded rod, a common size in commercial hanger systems\u003c\/li\u003e\n\u003cli\u003eDuctile iron construction for strength and impact resistance\u003c\/li\u003e\n\u003cli\u003eIntegrated locknut prevents rod from loosening under load or vibration\u003c\/li\u003e\n\u003cli\u003ecULus Listed, FM Approved, MSS SP-69 (Type 23), SP-58, and UL-U.L.C.

Ensure structural steel or beam flange thickness does not exceed 3\/4 inches before seating the clamp. Confirm the hanger assembly is fully de-loaded and the work area is safe before adjusting or repositioning the clamp. Follow applicable codes including IFGC, IPC, and NFPA 90A\/90B for hanger spacing and load requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Type\u003c\/strong\u003e: C-Clamp with Locknut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 400 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flange Thickness\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: cULus Listed, FM Approved, MSS SP-69 (Type 23), MSS SP-58, UL-U.L.C.
