GateKeeper is a steel roller coaster located at Cedar Point in Sandusky, Ohio. Designed by Bolliger & Mabillard (B&M), it was the fifth Wing Coaster installation in the world. The ride opened on May 11, 2013, on the most successful opening weekend to date in the park’s history. GateKeeper features the highest inversion in the world, with its 170-foot (52 m) Wing Over drop. It has broken several Wing Coaster records, including those for height, speed, track length, drop height and number of inversions. The coaster has a 170 ft (52 m), 40-degree inclined lift hill with a 164 ft (50 m) drop and features two support towers with keyhole elements that the trains travel through. Its top speed is approximately 67 mph (108 km/h). Firelands Electric installed the power to all the distribution equipment, control wiring, control devices, coaster lighting, station lighting and site lighting.
