Vacuum mounting cups from Wood's Powr-Grip® provide a reliable, temporary way to fasten radios, fish finders and other electronic equipment on almost any smooth, nonporous surface, such as metal or fiberglass boats. Available in a range of styles to cover most applications and capacity requirements, they can also be used to mount radio antennas, fishing poles, beverage holders, and much more. WPG mounting cups employ a threaded stud, tap or bail-style handle to secure accessories and equipment. These vacuum cups attach to either flat or curved surfaces, including boat windshields, windows and decks. 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, including metric size (such as M8 and M10).
Wood's Powr-Grip also offers a selection of vacuum cups equipped with articulated mounting heads, to provide infinite positioning and angling of cameras and other devices. For those who need our most flexible mounting option, we stock a wide range of RAM® mounting equipment, which works with WPG vacuum cups to address the specific mounting requirements of each application.
In addition, Powr-Grip's hand-held vacuum cups come in rust-resistant styles that are ideal for marine applications. These work equally well as "instant handles" for loading and unloading watercraft, tie-down points for securing coolers and other loads, or handles for working on the underside of boats.
