Why not just use the Stoller frame rest adapters that reduce the 10 frames to 9 frames, killing two birds with one stone, frame rest protection and spacing. I have them in every hive and super I own .no crowding and fuller honey combs. of course to each his own..
Bought 250 for .45 apiece from Rossman. now I see they are .65 apiece..got mine 6 yrs. ago. Beekeep getting expensive, huh?
