Mine are custom made and were purchased from Animal Plastics (That is before I met and started purchasing from Chris)
Chris also has great rack and if you pick up at shows, in that case if you pre-order he will build the size you need.
Both make great racks but there are disadvantage such as shipping and lead time, animal plastics lead time is 8 to 10 weeks, Chris is much shorter and he also does shows on the east cost which mean no shipping.
Thanks for the info! I really like the looks of Chris' racks I'll definitely inquire with him when I'm ready. I'd love a double wide version of his 8 high v18 rack that would work for my plans.
