Wiegmann WASPB Steel Hole Plug 1.23 Inch Knockout Seal

Product Description

The WIEGMANN WASPB is a steel hole plug designed to seal unused openings in electrical enclosures, junction boxes, and control panels. Made from alloy steel, it covers push-button holes, conduit knockouts, and other unused openings to block entry of dirt, dust, oil, and water. The plug fits a 1.23-inch hole diameter and installs with a simple push-in action, making it a fast solution for keeping enclosure interiors clean and protected. Electricians and panel builders commonly use this plug during new installations and service work when openings need to be closed off.

This plug is suited for use in residential, commercial, and industrial electrical enclosures where open knockouts or unused push-button cutouts need to be sealed. It is appropriate for any application requiring a low-profile, flush seal on a 1.23-inch diameter opening. The alloy steel construction holds up in light-duty environments where oil or water exposure is a concern.
