The anti-drip feature automatically retracts the plunging rod once the trigger is released to prevent excess dripping. The LED light illuminates dark work areas. The speed dial provides a setting for maximum and minimum flow rates. The quick connect inter-changeable canister trays allow the user to quickly change sizes. The gun also features a convenient hang hook for easy storage.
