It seats against the interior face of a box, panel, or enclosure wall to fill the gap left when a smaller-trade-size conduit or fitting is installed through a larger knockout. The washer is stamped from steel with a galvanized finish for corrosion resistance. Trade size is 3-1\/2 inches x 1 inch, with an inner diameter of 1-3\/8 inches and an outer diameter of 5 inches. Licensed electricians and electrical contractors install this fitting during conduit rough-in on rigid metal conduit and IMC systems.\u003c\/p\u003e\n\u003cp\u003eThis reducing washer is suited for use with rigid metal conduit and intermediate metal conduit systems in commercial and industrial electrical installations. It is used wherever a standard knockout size does not match the conduit trade size being pulled, allowing the installer to maintain a proper, code-compliant fit at enclosure entries. Typical applications include panelboards, junction boxes, pull boxes, and other metallic enclosures where knockout reductions are required. It is sold and installed individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTrade size 3-1\/2 inches x 1 inch reduces a larger knockout to accept a smaller conduit entry\u003c\/li\u003e\n  \u003cli\u003eInner diameter of 1-3\/8 inches and outer diameter of 5 inches for precise knockout fit\u003c\/li\u003e\n  \u003cli\u003eSteel construction with galvanized finish for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eCompatible with rigid metal conduit and IMC conduit types\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with rigid metal conduit and intermediate metal conduit systems requiring a 3-1\/2 inch x 1 inch trade size knockout reduction at metallic enclosures, boxes, and panelboards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician.
