The mounting hole locations on this set of side rails match Stern Pro machines. This side rail set will fit on Premium or LE machines. However, one of the middle mounting holes is in a different location. See secondary picture above for clarification.
Set includes 1 left button guard side rail (535-0902-01) & 1 right button guard side rail (535-0902-02).
Fits all Stern machines from 1999 to present. Total end-to-end length is 45.25".
Button hole is 1.55" in diameter, leaving 0.11" clearance around the flipper button for the possible slight flipper button misplacement on the cabinet during manufacture.
