Pinball Straps were designed for most modern pinball machines with folding backboxes. Generally speaking, most pinball machines produced after 1984 started to implement some form of hinge mechanism to allow the head to fold down for transport and storage. These straps have been tested on all the leading manufacturers including Stern, Bally, Williams, Midway, Data East, Premier, Gottlieb, Chicago Gaming, Spooky Pinball, and others. Midway Pinball 2000 machines (Revenge from Mars and Star Wars Episode 1) do not have folding backboxes. Pinball Straps were not designed to secure pinball heads and backboxes without hinge assemblies like wood rails, bingos, pitch N bats, wedge heads, mechanical machines and older machines without hinges. Our Pinball Straps are constructed of the finest materials available at the current price point. Each Pinball Strap includes a Pinball Straps keyring to help keep your keys safe and secure while moving or storing your machine.
