Coaching and skating kits every rink should have for practice and public skating.

I saw this sort of equipment at many of the rinks I have been at in Europe. There are small nets,
balls, pylons, obstacles, tires, skating aids and 4x4 hollow boards that can divide the ice into 2
rinks down the middle or across the red line, or into 3 rinks at each blue line or into 2/3 and 1/3
across one blueline.

Coaches have equipment for their practice that they check out (or just use if everyone is honest)
and then return for the next person.
At public skating they divide the ice for hockey and skating depending on how many of each
show up.

There is a pdf with pictures attached.

Thanks Kai,

I noticed the front corner has a block under it so the puck can slide through. Does the back support lie flat on the ice, or is it blocked up too?

Thanks again.
