The Maximum Series Bones Tunnel is a uniquely designed bridge piece which forms a suspended tunnel which connects two elevated deck platforms. But what makes this particular tunnel interesting is that it is constructed from separate plastic rings, with a small space between each of them. This gives the bridge a ‘bony’ appearance, similar to a ribcage. More importantly it makes the tunnel semi-transparent, so that kids inside of it can see their surroundings, while supervisors outside of it can see the kids. A frame of four metal sturdy metal bars run through each of the rings, making the bridge solid and durable, despite containing so many separate pieces. The plastic rings alternate between two colors, giving it a striped pattern. There are tons of possible color pairs which can be made, so be sure to look at our impressive list of color options.
