Gardner Bender 701 Knockout Seal Steel 1/2 Inch 100 Pack

Product Description

The GARDNER BENDER 701 is a steel knockout seal designed to close unused conduit knockouts in electrical enclosures, junction boxes, and panels. Sized for 1/2 inch conduit openings, it provides a secure, finished closure that prevents dust, debris, and pests from entering the enclosure. This package contains 100 seals, making it well suited for service vehicles, maintenance stock, and larger installation jobs. Licensed electricians and panel installers use these seals as a standard code-compliance step whenever a knockout is opened but no conduit is run. Steel construction offers durability in both indoor and light commercial environments.

These knockout seals are used in residential and light commercial electrical work wherever metal enclosures, load centers, junction boxes, or disconnect panels have unused knockout openings. A pack quantity of 100 supports high-volume panelboard rough-in work or ongoing service and repair operations where single-use seals are consumed regularly. They are a common carry item for electricians working to maintain NEC compliance on enclosure installations.

Installation Notes

Installation is performed by a licensed electrician. De-energize the panel or enclosure and verify absence of voltage before opening any electrical enclosure for service. Knockout seals are typically pressed or snapped into the open knockout by hand or with light tool pressure. Verify that all unused knockouts are sealed per NEC requirements before closing and re-energizing the enclosure.
