The MAXSA Innovations Park Right® BallPark helps you park your car in the right place every time. It's the “tennis ball on a string” meets the twenty-first century. The BallPark helps you prevent damage both to your car and your garage. Simply screw the included eye-hook into the ceiling above where you want your windshield to be when parked, then adjust the string so the BallPark hangs at a height where it will touch your windshield when you pull in. The ball creates a light show when it touches your windshield, letting you know you’re in the right spot. Get one for every garage or carport space!
