Halex 20605 Steel Knockout Seal Electrical Fitting

Product Description

The HALEX 20605 is a steel knockout seal designed to close unused knockout openings in electrical enclosures, junction boxes, and panel boxes. It blocks debris, pests, and moisture from entering the enclosure through open knockouts that are not occupied by conduit or fittings. The steel construction provides a durable, code-compliant closure. Electricians and electrical contractors install this seal as part of standard enclosure finishing work on residential and commercial electrical installations.

This knockout seal is used wherever an enclosure has an unused knockout that must be covered to maintain the integrity of the electrical enclosure. Common install locations include load centers, junction boxes, pull boxes, and disconnect enclosures in both residential and light commercial settings. Each unit is sold individually, making it easy to order the exact quantity needed for a job.

Installation Notes

Installation is performed by a licensed electrician following NEC requirements for enclosure integrity. Always de-energize the panel or enclosure and verify with a voltage tester before working inside any electrical box. The seal is typically pressed or driven into the knockout opening by hand or with a flat-blade screwdriver and a mallet. Ensure the seal seats flush and fully covers the knockout opening before returning the enclosure to service.
