In StockReady To Ship

Lockformer 20ga button punch snaplock. The button punch snap lock machine forms a two-piece seam that greatly simplifies ductwork assembly. The male seam is a button, the female seam is a lock, and the two snap together for a flush corner. Not only do these locks assemble twice as fast as traditional methods, but because the two pieces nest, they are easier to transport too.
