GETAWAY (Williams) Plastic shield set
Williams GETAWAY: HIGH SPEED II pinball machine 8 piece playfield plastic shield set.(All protectors are clear, image is tinted for contrast.)
Plastic protectors mount beneath flat artwork plastics and protrude about 1/8 inch around the perimeter of each printed artwork piece.
They're made from impact resistant PETG ((Polyethylene Terephtalate Glycol-modified) plastic to prevent ball damage to artwork plastics.
Thin enough to mount with existing fasteners, they are also clear and cosmetically unobtrusive.Reference:
