A specialist component designed for those seeking to fine-tune gameplay difficulty through targeted adjustments beyond typical modifications. Primarily intended for tournament directors, this adjustable coil stop enables subtle yet effective challenge increases by altering the flipper's end-of-stroke point.
The concept originated during servicing of a Jack•Bot machine, where worn coil stop replacement made gameplay noticeably harder without becoming unfair. This product captures that nuance with adjustability.
Stainless steel construction with a high-tensile steel alloy bolt, ground and polished for maximum surface contact with the coil plunger at end-of-stroke. A machined grub screw at tight tolerances secures the bolt with zero unwanted play. Sliding rail mounts provide compatibility with both Bally/Williams and Stern coil stop footprints. Field-tested in UK tournament machines.
