Your standard caulk gun is now officially obsolete! Unlike fully composite/plastic guns on the market which flex and bend with every trigger squeeze, causing a loss of energy and increasing your workload, the patents pending design on the HybridTech Series from Newborn eliminates that completely. The HybridTech Series utilizes steel and composite materials where they are needed, helping to increase your productivity. The HybridTech Series also comes equipped with a dual component comfort grip, a spout cutter and a seal puncture tool for added comfort and convenience.
