Halex Scott Fetzer 20605 Knockout Seal 1/2 Inch 4-pack

Product Description

The HALEX SCOTT FETZER 20605 is a 3-piece knockout seal designed to close unused 1/2-inch knockout holes in electrical enclosures. Each seal provides a clean, secure closure that keeps the enclosure interior protected from dust, debris, and incidental contact. The package contains 4 sets of 3-piece seals, giving electricians multiple units for a single job or stock. Rated for indoor use only, this seal is a standard item for any electrical rough-in or finish work where open knockouts must be closed per code requirements.

This knockout seal is used in residential and light commercial electrical work wherever metal or plastic enclosures have unused 1/2-inch knockouts. Typical applications include junction boxes, panel enclosures, conduit bodies, and equipment cabinets. Electricians and low-voltage installers use these seals during rough-in, remodel, and service work to bring enclosures into compliance with NEC requirements for closing unused openings.
