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.
