The HALEX/SCOTT FETZER 68720 is a steel reducing washer used to reduce the knockout opening size in steel outlet boxes and other metal enclosures. Sold as a single pack, it measures 2.5 inches by 2 inches and is manufactured from steel for durability in both indoor and outdoor applications. Installation requires one washer placed inside the enclosure opening and one on the outside, sandwiching the enclosure wall to secure the fit. Electricians use this washer when a conduit fitting or connector is smaller than the available knockout, allowing the box to be repurposed or correctly fitted without replacing the enclosure.
This reducing washer is suited for residential and commercial electrical installations wherever a steel outlet box or metal enclosure has a knockout that is larger than the conduit or fitting being installed. It is rated for both indoor and outdoor use, making it appropriate for service panels, junction boxes, and exterior enclosures. The steel construction holds up in conduit runs exposed to typical environmental conditions. It ships in a package quantity of 10, making it practical for stocking on service vehicles or in supply rooms.
Designed as an OEM-style replacement and standard-fit accessory for steel outlet boxes and other metal enclosures requiring knockout size reduction.
Installation is performed by licensed electricians in accordance with NEC requirements for conduit and box fill. Before installing, de-energize the circuit and verify the enclosure is not live. Place one reducing washer on the inside of the enclosure opening and one on the outside, then secure the fitting through both washers. Do not use a single washer alone, as both sides are required for a code-compliant and mechanically secure installation.
