Crab Grab Grab Rails are a throwback back to the days when people were only going upside down once per jump, and style reigned supreme. Back in these days snowboarders were grabbing so radically that their hands were slipping off their boards, and thus the grab rail was born. This two-fold utility piece acts as both a stomp pad and a surface to stick your mitts to when you're tweaking that grab beyond what should be humanly possible.
