The kit includes a stud bolt for secure mounting and alignment of the punches during operation, helping maintain stability as you form precise knockout holes and reducing the risk of misalignment during punching. As a Greenlee product, the 5004187 configuration reflects the brand's focus on reliable tooling for electricians, with punches designed to deliver consistent hole sizes that match common conduit fittings used in commercial and industrial installations. Common applications include creating knockouts in electrical panels, electrical enclosures, and related equipment housings, where having the appropriate diameters—1-1\/4-inch, 2-inch, and 3-inch—supports efficient conduit routing and wiring layouts.\u003c\/p\u003e\u003c\/div\u003e","brand":"GREENLEE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268916170986,"sku":null,"price":261.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-052.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/greenlee-5004187-knockout-puncher-with-stud-bolt","provider":"GTG Hardware","version":"1.0","type":"link"}
