Friday I received a order of medium frames and Monday I should get a order of medium wired foundation. I took the frames out of the shipping box a few minutes ago and found them to be the groove top and groove bottom, which is not what I ordered. The foundation that is comming is the type with the wire hooks at the top and the catalogs state this will not fit the groove top/groove bottom frames. OUCH! I am supposed to transfer some bees from NUCS on Tuesday and because of time I am in a bind. Can the wire hooks on the medium foundation be clipped off and the foundation still be mounted in the medium groove top/groove bottom frames or am I SOL on this project? Thanks for any help...
