As a check to moisture that may pass across the tie, the butterfly type is laid with the twisted wire ends hanging down into the cavity to act as a drip.
The double triangle tie may have a bend in the middle of its length and the strip tie has a twist as a barrier to moisture passing across the tie.
The butterfly is more likely to collect mortar droppings than the others.
Made of galvanized sheet steel for high resistance to corrosion.
