Here’s how to install a Rain-X Expert Fit beam blade on a PTB-type arm. First, remove the supplied adapter from the package. Next, insert the curved tab of the adapter into the square opening of the connector. Push down on the back of the adapter until it clicks into place. You’re now ready to install the blade. After you’ve removed the old wiper blade, make sure the wiper arm is in the up position. Then insert the bottom of the wiper blade connector into the opening on the arm and slide it down until the spring tab locks into place. Tug on the blade to make sure it is properly fastened. Finally, lower the arm gently onto the windshield. It’s that simple—you’re done. Affiliate link. We may be compensated.
