Buddy of mine is in the honey business. He's tried a couple other frame holders, but the issue that I see with them is that they aren't the exact same width as the supports that hold the frames when they pull the frame out. This version has offsets so they sit inside each corner but are offset to the actual width of the frames as they would sit in the box. He's tried these and really likes them so I thought I would put them up here for any other beekeepers that would find them useful. Definately want to print out of PETG or something that will withdstand being outdoors. The lip on these is just under 3/8 of an inch so they easily slip/set inside the box between the outside frame and inside edge of the box. He's going to send me a couple pics of them in his boxes and I'll add them here.
