The Crack Master Wonder Bar Bridge is the latest windshield repair tool from Ultra Bond. This tool handles both professional chips and long cracks. In it's initial form, as the bridge, the crack master is setup to handle repairing windshield chips with resins 2 to 5 times thicker than other tools on the market, which means more strength and durability. It can be split apart into a long crack slider and crack-opener to handle long crack windshield repair as well. There is a bolt in the middle of the bridge joining the Wonder Bar and the Long Crack Slider Complete Tool. What is great about Ultra Bond's Crack Master Bridge is that it is engineered better than any other tool on the market with the purest and controlled compression. This tool handles tension and compression better than any other because of length, size, shape, bolt placements, suction cup durometer and placement onto the bridge itself. Our unique design is best tool handling the compression and as a result enables our tool to inject structural adhesives and get an overfill into stone-break / chips and long cracks. This is key to actually being able to repair the chips and cracks in a windshield to 100% new glass strength and beyond new windshield strength. As you can start to see what professional windshield repair kit entails and that the Ultra Bond crack master wonder bar bridge was engineered to handle compression and enable you to take on more complex windshield repairs.
