It isn’t always easy to anticipate which grade of wiper arm will make the most sense for your particular use. There are so many variables that go into determining the most suitable wiper arm that it often takes a qualified engineer to get it right

You’ll need sturdier wiper arms on larger glass because those long arms and blades develop greater stress at the pivot connectors and on the tension springs.

The curvature of the glass is also an important variable – the farther away from flat you get, the more the arm will “rise and fall” through the sweep motion creating more wear on the wiper arm hinge and tension spring.

The conditions you expect your vehicle, vessel, or industrial cab to be operating under should influence you wiper arm choice too. Obviously, the frequency of wiper use will directly influence its longevity but sometimes, where you expect the wiper systems to be serviced should influence your choice.  A durable wiper arm might be a selling point a working boat will be serviced in rolling seas. And a vehicle operating at highway speeds needs a sturdier wiper arm, than a forklift.

Selecting the correct wiper arm is a matter of matching the arm to the individual needs of your application by weighing glass geometry, operating and service conditions, and price, of course.
