ZIP System liquid flash applicator has a steel frame that fits 29-ounce cartridges and an 18:1 thrust ratio for use with STPEs, acrylics, adhesives, asphalt, butyl, and cement. The revolving frame allows the barrel to rotate for maintaining the same bead orientation when caulking around corners. The smooth pressure rod requires less force and is quieter than a ratchet-style pressure rod. The zinc alloy handle and trigger provide corrosion resistance, and a seal puncture tool and a spout cutter are built into the side of gun for opening cartridges without a knife.
