No Gouge Pinball Rubber Playfield Jacks, Set of 2. Made of rubber to avoid scratching, denting. SO EASY TO USE: Designed to hold the playfield on most modern pinball machines, can be used as a pair, or 2 sets can be used to support all 4 corners in most cases. Fits all modern cabinets, with clearance for side blades in most cases. These are useful with modern games where the rear of the playfield can be lifted and set securely on these jacks, but these are also amazingly useful on older games to suspend the front of the playfield in a position not offered by the factory prop bar, or to hold the rear of the playfield and front of the playfield at the same level for the best access to change plastics, do shop work or servicing, cleaning. Great Colors to Match or Contrast Your Game or Mods
