Vulcraft PunchLok II System


Vulcraft PunchLok® II System

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.

VULCRAFT’S PUNCHLOK® II SYSTEM GETS THE JOB DONE RIGHT.

  • A weld-free system when used in conjunction with mechanical fasteners at supports.
  • As strong as top seam welds in most applications, but installs up to 10 times faster.
  • Requires no touch-up from either the topside or the bottom side of the deck.
  • Accuracy of the attachment can be inspected from the deck’s topside and requires no inspection tools or gages.
