A set of four plastic legs that attach to the Ultimate Bottom Board. To attach them, remove the feet that come with the bottom board, slip the legs in, and then re-attach the feet to the legs. With the legs in place the hive entrance is about 7-1/2" off the ground. There is a reservoir of a veggie oil to prevent ants from entering the hive.
Absolutely love the ultimate bottom board. After adding the leg extensions I had the same problem with drowned bees, but really liked the additional height. I drilled a hole halfway up the cup to prevent them from filling with water every time it rains. No more drowned bees.

Not a good product
I had at least 100 bees drown in the first 24 hours after installing these legs. The only reason I did not lose more was the ant traps were completely full of dead bees. BMB Farm should pull this product right away.
