Suitable combination for arm, blade and wiping angle.
In order not to overload the RWS type motor, it must be checked that the combination of arm length, blade length and wiping angle is acceptable.
The result of the sum: wiper blade length (mm) x arm length (mm) x wiping angle in degrees should not exceed 17,800,000.
Example:
Blade length : 410mm
Arm length: 366mm
Wiping Angle: 120 degrees
410 x 366 x 120 = 18,007,200
which means that this combination is not allowed
The metal parts of these wiper arms are made of high gloss polished stainless steel (AISI 316) and the black components are made of top grade synthetic materials.
The dual wiper arms are available in two sizes:
AD: from 308 mm to 393 mm
ADX: from 386 mm to 471 mm
Wiper blades may be fitted in one of two positions on the dual wiper arms, so that the wiped surface can be adjusted. The dual wiper arm spindle centres are 45mm.
