At this time the Ant Barrier is only offered in one size.   If you have a Food Holder that is too large for one Ant Barrier, you can do one of two things:

1) Use multiple Ant Barriers.

2)  Purchase the "Sani-Moat Ant Barrier with Expander Legs".
Q:  Is the Ant Barrier offered in different sizes?
The "Expander Legs" attach to the bottom of the moat for better balance for larger Food Holders.  You can use this for Extra Large Bowls, Trays, Platters, Bulk Food Containers, Planters, Trash cans and other large Food Holders.
