The Vulcraft PunchLok II System utilizes a specially designed pneumatic tool to achieve higher shear values at less cost through high quality side seam attachments. Used in conjunction with Vulcraft’s interlocking products, the PunchLok II tool is fast, effective, and provides a stronger and more positive attachment than screwed sidelaps or conventional button punches. It also provides excellent lateral diaphragm action, minimizes steel deck attachments, and potentially reduces steel deck gage. The PunchLok II system is designed to be used Vulcraft’s 1.5PLB™-36, 3PLN™-32, 3PLN™-24, 1.5PLVLI™-36, 2PLVLI™-36, and 3PLVLI™-36 steel deck.
