These pull tabs are designed to give a very hard pull. The tabs feature a conical collar and larger pulling head that gives extra strength. They don't flex when you use them and are ideal for small, sharp dents. They are excellent to use with both a slide hammer and a robo-lifter for when you need a sharp snapping pull. They come in 3 different sizes, and you receive 3 of each. Please see the photos for the dimensions.
