Be aware that the 8-frame feeder currently sold by Rossman is a 5-frame feeder mounted in a frame that fits on 8-frame boxes.
It doesn't resemble the photo on their website.
I discussed my displeasure over ordering eight frame feeders and getting feeders with the capacity of 5-frame feeders. Mr. Rossman understood and offered to take them back.
They would be OK for someone with a hive or two in a backyard, but some of my hives are 20 miles away and I need the full capacity of a true 8-frame feeder.
