This is a cover for the naked coil that diverts the ball onto the crossbow lane when the feature is qualified. There are five color options, Gray, Gold, Black, Red, and Brown. The cover slides onto the coil and is pressure-fit with the ramp hole sides. It may be necessary to loosen the two screws on top holding the coil bracket to slide the cover on and then re-tighten and align the bracket once the cover is on.
