Dripless CR400 Contractor Cradle Frame Ratchet Drive Caulk Gun - 29 oz Cartridge Capacity - Caulking Gun with Machined Ratchet Teeth - Ladder Hook, Seal Punch and Cutter Built in - Contractor Grade

The Dripless CR400 Contractor Grade Cradle Ratchet Drive caulking gun has a steel half-barrel frame that fits 1-quart cartridges (cartridges not included) and can be used with materials such as latex, vinyl, acrylic, siliconized acrylic, and silicone. The ratchet-style pressure rod has teeth that hold the rod in place after each pull of the trigger. For thinner materials, this helps minimize drips. The hook on the back allows it to hang on a ladder, and 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.
