Product Description The Newborn U-Lite Non-Drip Super Smooth Rod Frameless caulking gun fits 1/10-gal. cartridges and has a 10:1 thrust ratio for use with low and medium viscosity materials such as latex and silicone. The frameless design is compact and lightweight and allows the cartridge to rotate for maintaining bead orientation when caulking around corners. The smooth pressure rod requires less force and is quieter than a ratchet-style pressure rod. The rod retracts after each pull of the trigger, removing pressure from the tube to help prevent dripping. A seal puncture tool and a spout cutter are built into the side of the gun for opening cartridges without a knife. Caulking guns, also called caulk or cartridge guns, dispense a controlled flow of products such as caulk, sealants, and adhesives from a tube or cartridge. A manual caulking gun consists of a frame which holds the tube, a trigger, and a rod which moves forward when the trigger is depressed, dispensing the product. Manual caulking guns have a thrust ratio; the higher the thrust ratio, the easier it is to dispense the caulk, sealant, or adhesive. Air-powered or pneumatic caulking guns also have a frame and a trigger, but are used with an air pressure regulator that pushes the product from the tube using air pressure instead of a rod.
