The P12 arms are specially designed for the powerful 280BS and 2110BS wiper. The Exalto P12 arm will be manufactured to the required length. Please, note that therefore they have a longer delivery time. The P12 is not adjustable in length. The P12 arm is made of stainless steel 316 and has seawater resistant brass heads. A black coating is applied as a standard to prevent reflection. The Exalto P12 arms have two adjustable springs, to adjust the pressure on the glass steplessly. By means of the swivelling blade clip, you can park your blades parallel to the window. We advise you to use the Exalto Heavy Duty (H.D.) blades in combination with this arm.
