Thanks, Doak - see what I mean about math!

Actually I only have 50 frames, so maybe
counting is my problem as well as math! I'd like to order the end bars from the same manufacturer but I bought them from Dadant who doesn't appear from their website to sell the end bars separately.
Not only do I have those in my basement but I also have a set of 10 deep frames that I won as a Bee meeting door prize and thought I'd never use - but now I can at least use the top and bottom bars.
