National Mfg N180-141 Slotted Flat Bar 1.375x72 Steel

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N180-141 is a galvanized steel slotted flat bar measuring 1.375 inches wide by 72 inches long, sold in a package of two. It is designed for sturdy hanging or bracing applications in mechanical, plumbing, HVAC, and general construction installations. The slotted hole pattern is punched to align with standard slotted angles, allowing fast, accurate assembly without field drilling. The corrosion-resistant galvanized finish makes it suitable for use in areas where moisture exposure is a concern. HVAC technicians, plumbers, and general contractors use this flat bar for equipment support, pipe hangers, duct bracing, and structural framing tasks.

This flat bar is suited for both residential and light commercial applications. It is commonly used to hang or brace mechanical equipment, support piping runs, and build out utility framing assemblies where slotted angle systems are already in use. The pre-punched hole pattern eliminates layout time and ensures consistent hole alignment when mating with compatible slotted angle components. Each package contains two bars, making it practical for jobs requiring paired supports or symmetric bracing runs.

Key Features

• Pre-punched slotted holes align with standard slotted angle hole patterns for tool-free layout
• Corrosion-resistant galvanized finish for use in damp or humid environments
• 1.375-inch width by 72-inch length provides versatile reach for most hanging and bracing tasks

• Sold as a package of two bars for paired or symmetric installations

Compatibility

Designed for use with slotted angle framing systems where hole patterns are punched to standard spacing. No specific model compatibility was stated in the product data.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or general contractors as part of a mechanical support or framing assembly. Power down or de-energize any nearby equipment before working in close proximity to live systems. Use appropriate fasteners rated for the load being supported, and follow applicable building and mechanical codes for hanger and brace spacing. Do not exceed the structural load limits of the bar or the slotted angle system it is paired with.
