The Blackriver Iron Low Construct is a rail that can be added to existing features you already have, or can be used as a standalone obstacle. The rail's small feet will need to be drilled down with the included screws in order for the rail to be used to its full potential. Blackriver suggests Box 3 as the perfect pairing, but you can really fit this into any obstacle or park you have. In case you clicked on this by mistake, we want to be clear. This product is meant to be used with fingerboards. You know teeny tiny skateboards for your fingers. NOT full-size skateboards.
