Transformer Double Jam

by: Transformer Rails

The Double Jam is the perfect rail for learning all pole jam tricks! Features a 3” flat bar on one side at a mellow 35 degrees and a steeper round rail on the other side at 55 degrees. The Double Jam is heavier than other pole jams, which makes it more sturdy when grinding. The Double Jam can also be permanently mounted to wood or concrete using the pre-drilled holes in the feet.
