Sealant guns make it easy to apply a smooth, even line of silicone or mastic to a surface or gap. The sturdy frame holds the tube firmly in place, allowing for simple unloading with no slippages or mess. Also known as a caulking or skeleton gun, there are heavy duty models available that have a reinforced, riveted frame to give additional durability and can hold heavier cartridges. Some have an ergonomically-designed dipped handle that is comfortable during long periods, along with a high-thrust trigger with adjustable screw for a free-flowing action. Choose from a selection of sealant guns that are designed to fit a variety of cartridge sizes.
