All my hangings come with a 9" chain built into the piece. If you are hanging your Prisma from the ceiling, rather than the wall or the window sill, you might need an extender!
These have a hook on one side (that you will attach to the ring on your original Prisma), and a ring on the other side, to attach to a hook or other hanging system that you might have. There are different lengths available.
Available only with the purchase of a Prisma Hanging.
