Yup, its a double height rail, that works perfectly with a ramp a LOT of people have, BRR box 3. Its great to see rails coming out that allow for more creativity with obstacles and people using more obstacles at a time. There are soo many different ways I can think to use this rail.. and also if you build a park and make a stairset, raise a teeny bit at the bottom and you could use this as a flat rail for the stairs! Loads of posibilities. They'll come with two screws to screw into the ramp on the shorter end, so it'll be nice and secure.. Personally I wouldn't want to make holes in my box 3, so I'd use bluetak, but I guess its cool that the option is available!
Definitely go check out the airflo site, these might be available soon, but otherwise they always have great rails available :)
