SJJ 2" Gray Hand Tools sku-17520671438 617367476159

SJJ Gray 2" conduit knockout unit, sku-17520671438 and UPC 617367476159, is a Hand Tools item supplied with a manual draw stud. It makes a 2.42" hole and can be operated with a ratchet, wrench or electric driver. It punches mild steel plate up to 10 gauge (3.5mm) and can also be used on copper, soft aluminum alloys, fiberglass and plastic.

A secondary cutter splits the slug so its pieces can drop out of the die. The die is designed for smooth edges and consistent hole size. The manual design suits confined spaces, and engraved markers help with alignment during electrical or metal-fabrication work.
