Eaton bh4-f4 Z-purlin Flange Hanger 1/4 in Threaded Rod

Product Description

The EATON bh4-f4 is a Z-purlin flange hanger designed to support 1/4-inch all-threaded rod from Z-shaped structural purlin flanges. It provides a fast, code-friendly attachment point for suspending conduit, pipe, duct, or cable tray from steel purlin framing. The hanger carries a rated load capacity of 160 pounds and measures 1 inch in height, 1 inch in length, and 1 inch in width, weighing 0.07 pounds. It is manufactured in the USA and carries UL approval for both Canada and the US. Licensed electricians and mechanical contractors install this hardware during rough-in on commercial and industrial projects where threaded rod drops are required from light-gauge steel framing.

The bh4-f4 is suited for commercial and industrial construction applications where threaded rod runs must terminate at Z-purlin steel framing members. Typical install scenarios include hanging electrical conduit support systems, unistrut assemblies, and mechanical piping runs from roof or mezzanine purlin structures. The hanger clips onto the flange of the Z-purlin and receives a 1/4-inch threaded rod, eliminating the need for drilling or welding the structural member. It is packaged 100 units per box, making it practical for large-scale commercial projects requiring consistent, repeatable rod drop installations.

Designed for use with Z-purlin flange framing in commercial and industrial construction. Accepts 1/4-inch threaded rod. No additional compatible model numbers are specified in available product data.

Installation Notes

Installation is typically performed by licensed electricians or mechanical contractors during structural rough-in. Before installing any threaded rod support system, confirm the purlin framing is de-energized if adjacent to live electrical infrastructure and verify structural load ratings with the project engineer of record. The hanger should be fully seated on the purlin flange before threading the rod through to ensure proper load transfer. Reference NEC Article 300 and applicable local mechanical codes for conduit and piping support spacing requirements.
