The QUICKSILVER 3X4 Adjustable Wide-Body squeegee with its patented four settings is our most durable model. It has 40 degree diagonally angled ends (and 90° ends on 10″ and shorter sizes) which 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. The adjustment slots or settings in the Sörbo 3X4 Adjustable squeegee channel allow you to reposition the rubber/blade to the preferred firmness. For 36″ squeegee set rubber to 2nd adjustment. Accompanied with the Sörbo Fast Release handle, Item 1385, you have a 40° angle. In order to prevent streaks on the window, lead with the top of the squeegee. Sörbo invented this revolutionary wide body squeegee longer than 24″ and up to 36″ in 1986. Note: All of these squeegees have their size (in/cm) imprinted on them next to the Sörbo logo.
