Quoted from Rarehero:

You don't need those leg protectors! Stern games have standoffs now so the legs never touch the cabinet. Those protectors are more likely to damage/wrinkle the cabinet decals than protect anything!

Quoted from Rarehero:

The first decal Stern cabinet was TF...and they wrinkled right away. Starting with AC/DC, they added the standoff cabinet protectors, so yes, now every game is protected from the factory...the leg will never directly touch the cabinet decal.

...as long as they're also raised by the standoff and not touching the cabinet decals. If they're touching the decals, those decals will wrinkle.
