Ag Manufacturing 315 Knockout Seal 2in Stamped Steel 3pc

Product Description

The AG Manufacturing 315 is a 3-piece knockout seal with a screw back strap, designed to close off unused knockout openings in electrical enclosures, panels, and junction boxes. Constructed from stamped steel, it provides a durable, low-profile closure that meets typical trade installation standards. At 2 inches, it fits standard 2-inch knockout cutouts and secures firmly in place using the included screw back strap. Electricians and panel technicians rely on this type of seal to maintain enclosure integrity, reduce debris ingress, and keep installations code-compliant. The stamped steel construction holds up in both indoor and light commercial environments.

This knockout seal is suited for residential and commercial electrical work wherever unused 2-inch knockouts need to be closed. Common applications include load centers, meter bases, disconnect enclosures, conduit bodies, and general-purpose junction boxes. The 3-piece design allows for quick field installation without specialized tools, making it practical for service work, panel upgrades, and new construction rough-in. It is typically installed by licensed electricians or qualified maintenance technicians as part of standard enclosure finishing work.
