Does anybody use or know where I can get the "Side "T" looking frame rests? I used to have them on my brood chambers back in the 80's. Now I have new equipment and non of them use the "T". I just won a free hive at my beekeeping club but the groove for the frame rest is too deep and the space above the frames is close to 1/2". I remember that way back when I used to have the "T"'s I had little problem with bees propolising the end bars and it made it easier to pry the frames up w/o damage.
