Wax foundation used by modern beekeepers to give bees a uniform guide to build the comb in turn helping increase honey production. Wire embedding makes foundation stronger and allows for centrifuge extraction. Wax foundations are made in various sizes, depending on the frame they will be inserted into. The British Standard wired and unwired 14X12 foundation fits National and WBC deep brood frames (DN12 frames). All foundation packs are available as wired or unwired in packs of 10 sheets.
