Anvil 0500009337 C-clamp Locknut 230 Lb 3/4 in Flange 3/8 in Rod

Product Description

The ANVIL 0500009337 is a C-clamp with locknut designed for securing threaded rod to structural flanges in mechanical, plumbing, and HVAC piping support applications. Built from carbon steel and ductile iron with a plain or zinc-plated finish, it accepts up to 3/4 inch flange thickness and 3/8 inch rod diameter. The locknut secures the rod position after installation, preventing vibration-induced loosening. Rated at 230 lb load capacity, this clamp is sized for light- to medium-duty pipe hanger and support assemblies where cULus Listed and FM Approved hardware is required by code or specification.

This C-clamp with locknut is used in commercial and residential mechanical systems to attach threaded rod hanger assemblies to beam flanges, angle iron, and structural steel. Typical applications include HVAC ductwork support, hydronic piping hangers, sprinkler system support, and general mechanical piping installations. It is installed by pipefitters, plumbers, HVAC mechanics, and fire protection contractors working from overhead structural members.

Installation Notes

Installation is performed by licensed pipefitters, plumbers, or HVAC mechanics following applicable mechanical codes such as the IPC or IFGC. De-energize and depressurize any adjacent systems before working overhead. Seat the clamp fully onto the flange before tightening the locknut to secure threaded rod position. Verify the installed assembly load does not exceed the 230 lb rated capacity of the clamp.
