Our Universal Wiper Puller has two sets of interchangeable arms and is made of hardened steel.
To Use first set the wiper puller arms on the horizontal slide. Then slide them in until they touch the side of the windshield wiper. Snug the wing nut to hold them in place. Use a wrench or ratchet to tighten the bolt that contacts the wiper nut. Then, remove windshield wipers.
