Re: Wedge top bar frames instead of groove top bar OK?
Wedge top bars will work fine with the plastic foundation. Just mount the plastic foundation in the frame with the wedge just like you would all wax foundation. Another beekeeper gave me a box of the plastic Perma Dent foundation, but all of my frames are wedge style. I just popped out the wedges, inserted the foundation, and tacked the wedge in just like I do with all wax foundation. It will be less convenient to replace the foundation than it would be with grooved bars, but it will work.
