Wood's Powr-Grip® mounting cups provide the most stable and reliable way to attach windshield repair fixtures and expander bars on any glass surface. Available in a range of styles to cover most applications and capacity requirements, they can also be used to mount lights, reflector boards and leverage straps for paintless dent removal (PDR). Most WPG mounting cups employ a threaded stud or tap to fasten devices. These vacuum cups attach to flat or curved surfaces of cars, trucks and SUV's. Since Powr-Grip mounting cups attach and release in seconds, they can be moved quickly from one place to another, without damaging most surfaces. Studs are available in various lengths and threads, to fit a variety of applications.
Wood's Powr-Grip also stocks a wide range of RAM® mounting equipment and other accessories, which work with WPG vacuum cups to address the specific requirements of your application.
