The Bont Block is a high performance slide block designed specifically for the Prodigy and Tracer plates. 

The edge of the block was carefully designed to ensure smooth sliding on any surface. Whether you skate flat-footed or angle your feet, the Bont Block will lock you onto the coping or ledge without the risk of slipping out. Yes, unity slides are possible with Bont Blocks.

The Bont Block size matches the Tracer/ Prodigy plate size. For example, if you have a size 6.5 Tracer plate, you will need a 6.5 Bont Block. You can find the plate size on the plate near the back pivot cup. Note: Plate size is different to boot size.

Sizes: 5.5", 6.0", 6.5", 7.0" and 7.5"
Block material: High polymer polyethylene
Metal bar material: Powder coated steel
Though the Bont Block is made for the Bont Tracer or Prodigy plate, may fit other 20-degree plates and other plates with bar modification. However, any modification will void your warranty.
