This bracket substantially reduces or eliminates airballs from standup targets by a combination of height and angle adjustment of the bracket at rest. It reduces or eliminates airballs, even on famously airball-heavy games like Ghostbusters.
This is the newest version of the bracket developed originally by Swinks. The original bracket was printed metal that became very expensive over time due to price increases by the printing service, so it was redesigned as a stainless steel bracket with a license from Swinks. Quantity manufacturing of this allowed the price to be cut by more than half compared to what it was, and deliver a polished stainless steel bracket that functions the same so more people can experience the impressive difference these make in machines plagued by standup target-launched airballs.
This is the only way to concretely address the problem because it changes the angle AND the height of the bracket. 3D printed wedges address the angle, but change the height incorrectly, so not a proper solution.
Installation is simple. Unscrew the existing target plate from the switch stack, replace it with this, and attach with the same screws you just removed. Done. Expect about a 10 minute or less job per target.
