Au-ve-co Products 3755 Finishing Plug 7/8 Inch Round Button

Product Description

The AU-VE-CO PRODUCTS 3755 is a round button-style finishing plug designed to close and dress 7/8-inch holes in sheet metal and panel assemblies. Made from spring steel with a nickel finish, this plug snaps into place by spring tension, providing a clean, flush appearance without fasteners or adhesives. It accommodates panel thicknesses from 0.031 to 0.093 inches, making it well suited for light-gauge sheet metal work commonly found in HVAC enclosures, electrical cabinets, and equipment panels. HVAC technicians, electricians, and sheet metal workers install these plugs during equipment assembly or field service to cap unused knockouts and access holes.

This finishing plug is used in residential and commercial applications where unused panel openings need to be closed off neatly. Typical installations include HVAC unit enclosures, electrical panel knockouts, and control cabinet penetrations. The spring steel construction allows the plug to grip the panel edge securely across the supported thickness range. Minimum order quantity is 50 pieces, sold individually per package.

Installation Notes

Installation requires no tools - the plug is pressed into the hole by hand until the spring steel tabs engage the panel edge. Verify panel thickness falls within the 0.031 to 0.093-inch range before installation to ensure proper retention. Power down or de-energize any electrical enclosure before inserting plugs into live cabinet panels. Once seated, the plug is not intended for repeated removal without risk of deforming the retaining tabs.
