The Greenlee 7306SB is an 11-ton hydraulic knockout kit (½" to 2" conduit size) with a hand pump and Slug-Buster® punches & dies. It cuts up to 10 ga mild steel or 12 ga stainless steel, featuring a compact, lightweight design for one-person portability. Knurled punch edges, alignment marks, and dog-point draw studs reduce cross-threading.
