Eliminates the Need to Remove Molding, Windshields or Quarter Glass Panels Reaches Areas You Never Thought Possible Pays for Itself After First Use Designed by an auto glass expert, the CRL Problem Solver Nozzle is eight inches (203 millimeters) long and eliminates the need to remove moldings, windshields or quarter glass panels to fix leaks. Its narrow tip allows it to fit behind moldings, headliners and dash tops, applying urethane directly to the leading area from inside or outside the auto. It's a real time and money saver because it can pay for itself after only one use. Problem Solver Nozzles fit virtually any caulking cartridge by sliding over the existing nozzle, or screwing onto the threaded nipple. Choose from either Rigid or Flexible nozzles, or order the Combo Pack with two flexible and two rigid nozzles. Note: Warmed sealant flows easier and fills the void rather than bridging the void. Length: 8 in (203 mm) Minimum Order: 1 Package 4 nozzles per pack. (2 rigid and flexible)
