A friend stopped by yesterday morning to pick up a nuc, he's a new beekeeper. We slid the nuc into the topper on his truck and sat talking bees for a while. Anyway, he had some beeware in his truck and i was "demonstrating" a bit when i got to looking at his bottom board. The BB's I've seen have all had 3/4 inch rails. This one had 3/8 inch rails. Sup with that? Ted
Edit to add: 3/4x3/4 vs. 3/4x3/8
