This is yellow rite-cell waxed foundation for a regular, deep, Langstroth hive box. I always suggest that you still swipe a bit of warmed wax (take a piece of wax scraped from the top of a frame while cleaning up during an inspection, and do a “Zoro” swipe) over both sides of the frame before adding it to your hive. This will invite the bees to investigate and want to clean up your mess and I find it encourages the bees to draw out the frame.
