Greenlee 7212SP-3D Conduit Round Die 3 in 3.53 in Hole

Product Description

The GREENLEE 7212SP-3D is a round conduit die designed for use with the Greenlee SPEED PUNCH System. It produces a clean, accurate hole sized at 3.53 inches in diameter to accept 3-inch conduit. The die is a replacement component intended for electricians and pipe-fitting tradespeople who rely on the SPEED PUNCH platform for fast, high-quality knockouts in enclosures, panels, and sheet metal. Its round profile ensures a true circular cutout with consistent results across standard installation materials.

This die is suited for commercial and industrial electrical work where 3-inch conduit penetrations are required in electrical enclosures, junction boxes, and similar metalwork. It is a dedicated replacement component for the SPEED PUNCH System, making it appropriate for job sites and service shops that already operate Greenlee SPEED PUNCH tooling. The 3-inch conduit size is commonly encountered in medium- to large-scale electrical distribution and service entrance installations.
