Klein Tools 53849 Knockout Punch 1-1/4 in Conduit

Product Description

The Klein Tools 53849 is a knockout punch designed for creating clean, accurate 1.701-inch diameter holes in electrical enclosures, panels, and junction boxes to accept 1-1/4 inch conduit fittings. This type of punch is a standard tool in commercial and residential electrical work, used to punch through sheet steel and aluminum without distortion. It delivers a precise, burr-minimized opening that meets conduit entry requirements. Electricians and wiremen reach for knockout punches when adding conduit entries to existing or new enclosures, keeping work clean and code-compliant.

The 53849 is suited for use in electrical panel work, pull boxes, wireway enclosures, and equipment cabinets requiring 1-1/4 inch conduit entries. It is commonly used in commercial construction, industrial facilities, and residential service upgrades where multiple conduit entries must be added to metallic or non-metallic enclosures. The punch is operated with a draw stud and hydraulic or manual driver depending on the installer's tooling setup.
