Feeder Station Angle

[DjScribbles]

All of the FEEDER STATIONS consist of a 44 in. wide shield of clear polycarbonate. In the center of the shield are three horizontal FEEDER SLOTS, 12 in. wide by 3 in. high. These slots are located 22 in., 42 in. and 62 in. from the FIELD carpet to the bottom of the slot. Each slot has a slide attached to it on the FEEDER side of the plastic. These slides are 8 in. long and are at a 30-degree incline.

Emphasis mine. It's in the game manual (section 2.2.7), rather than the drawings
