Rail buttons are used in place of launch lugs to guide the rocket off the pad. They are used on BIG rockets, where additional support is needed to prevent the rocket from swaying until the rocket reaches sufficient speed where the fins will guide the rocket. The Large Rail Button is designed for a 1515 rail and rockets approximately 10lbs or larger.
