Newborn 624 GTS Bulk/Sausage/Cartridge Deluxe Hex Rod Caulk Gun

The Newborn 624-GTS Deluxe Smooth Hex Rod caulking gun fits 24 oz. bulk caulk or a 10 oz. or 20 oz. sausage pack and has an adjustable thrust ratio of 7:1 or 14:1 for use with low, medium, or high viscosity materials such as latex, silicone, acrylic, adhesives, asphalt, butyl, and cement. The revolving frame allows the barrel to rotate for maintaining the same bead orientation when caulking around corners, and the lock holds the barrel in place when rotation isn't necessary. The smooth pressure rod requires less force and is quieter than a ratchet-style pressure rod, and the handle and trigger are padded for comfort. The caulking gun includes one floating hytrel cup for use with sausage packs, one ring cap for attaching nozzles, three plastic cone nozzles, and one 1/2" diameter metal nozzle.

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.
