The Dripless ETS6000 Industrial Grade Sausage caulking gun has a 2-1/8" Dia composite rotatingbarrel that can accommodate 10 Oz or 20 Oz sausage packs and has an 18:1 thrust ratio for use with silicone, latex, drywall, sub-floor adhesives and polyurethanes. The gun has both drip and non-drip settings. On the non-drip setting the rod retracts after each pull of the trigger removing pressure from the tube to help prevent dripping. The revolving frame allows the barrel to rotate for maintaining the same bead orientation when caulking around corners. The composite barrel and neoprene plunger are lightweight and provide corrosion resistance. A seal puncture tool and a spout cutter are built into the side of the gun for opening cartridges without a knife.
