Heavy gauge steel construction. Optional heavy-duty pins for installation on dirt surfaces (sold separately). Insert the included spikes in the 14-tapped holes for optimum anchoring. 36” long, longer than most, for easy adaptation to the tall or short runner without being moved. Powder coated pedals and zinc plated rail assembly for long lasting, new appearance. Pedal adjusts by tilting and sliding along the runner. Pad color may vary.
