Klein Tools 53857 1-1/2 in Conduit Knockout Punch

Product Description

The KLEIN TOOLS 53857 is a knockout punch designed to cut clean, accurate holes for 1-1/2 inch conduit installations. The punch produces a 1.951-inch knockout opening in electrical enclosures, panels, and junction boxes. Electricians and electrical contractors use this tool when adding conduit entries to sheet metal boxes, load centers, and other thin-wall enclosures. The forged construction and precision-machined cutting edge deliver a burr-free hole that seats conduit fittings cleanly without additional filing or grinding. At 0.4 pounds, the punch is compact and easy to handle in tight panel spaces.

This knockout punch is suited for use in residential and commercial electrical work wherever conduit entries must be field-added to enclosures. Typical applications include adding circuits to existing panels, roughing in new junction boxes, and modifying enclosures during service upgrades. It is used by licensed electricians working under NEC requirements for proper conduit support and entry fitting installation.
