Sorbo 45 Degree Viper Channel- The VIPER 45 is our 3X4 Adjustable Wide-Body Quicksilver squeegee with the patent ends cut at a 45° angle. The VIPER 45 still has the high quality that Sörbo is known for and the popular easy-on, easy-off Sörbo end clips which give you easy access when changing the rubber blade. The new 45 degree diagonally angled ends on the front and back of the channel help to prevent the tip of the alloy from coming into contact with the frame surrounding the window. It cleans closer to the frame leaving less water and reaches into the corners. It is perfectly suited for the S-technique. The squeegee rubber is secured with two exterior end clips which are also angled to its 45° cut ends. The adjustment slots or settings in the Sörbo 3X4 Adjustable squeegee channel allow you to reposition the rubber to the preferred firmness. It is sold with Sörbo FIRM45 T-shape rubber only which also has 45° angle cut ends.
