Eaton BH4-F4 Z Purlin Flange Hanger 1/4 in Rod 160 Lb

Product Description

The EATON BH4-F4 is a Z purlin flange hanger from the B-Line series of all-threaded rod and drop wire supports. It is designed to attach a 0.25 inch threaded rod to a Z-profile purlin flange, suspending pipe, conduit, duct, or cable tray from structural steel in commercial and industrial buildings. The hanger measures 1 inch in height, 1 inch in length, and 1 inch in width, and weighs just 0.07 pounds. Rated at 160 pounds load capacity, it provides a secure mechanical connection without welding or drilling into the purlin. Electrical contractors, plumbers, and mechanical trades use this fitting wherever threaded-rod hangers must be anchored to Z-shaped secondary framing members.

This hanger is suited for light commercial and industrial construction where Z purlin secondary steel is used as the primary suspension point. Typical applications include suspension of EMT conduit runs, small-diameter pipe, cable tray, and HVAC duct hangers from roof purlins or wall girts. The compact one-inch profile allows installation in tight flange clearances. It accepts 0.25 inch all-threaded rod, which is the standard rod size for lighter suspended-load applications governed by seismic and building codes.

Key Features

• Accepts 0.25 inch all-threaded rod for standard suspended-load installations
• 160 pound load capacity for reliable support of conduit, pipe, and duct
• Compact 1 inch x 1 inch x 1 inch envelope fits tight purlin flange clearances
• Lightweight at 0.07 pounds, minimizing cumulative dead load on the structure
• No welding or drilling required for attachment to the purlin flange
• Part of the Eaton B-Line series, a widely specified support system in commercial and industrial construction

Compatibility

Designed as an OEM-style hanger fitting for use with Z-profile purlin flanges in commercial and industrial suspended support systems using 0.25 inch all-threaded rod.

Installation Notes

Installation is typically performed by licensed electrical, mechanical, or plumbing contractors in accordance with applicable building codes and NFPA 70 (NEC) or ASME B31 requirements for supported systems. De-energize and de-pressurize any adjacent systems before working overhead. Verify the purlin flange profile matches the Z-clip geometry and confirm the installed rod and hardware assembly meets the required load rating for the suspended system. Do not exceed the 160 pound rated load capacity of this hanger.
