The PF arms are specially designed for wiper motor 240BS. Exalto PF arms are available for standard blades to 800 mm in length, or for H.D blades to 900mm in length. The arm is manufactured from stainless steel 316 and has brass, seawater resistant heads. The PF arms are fixed length and fixed spring pressure as a standard. The PF arm as standard has a swiveling blade clip to allow easy adjustment of the position of the blade in relation to the window configuration. The arm has a black coating to prevent reflection as a standard. However, these arms with fixed springs are also available in high polished stainless steel. The PF arms with fixed springs can be folded back, which allows it easier to mount the arms, change the blades or clean the window. Alternatively HD1 P10 arms can be used.
