BSBritish Standard — 14×12 deep brood11Sheets per packWiredEmbedded wire for comb strength Tier 3 — Frames & FoundationPremium wired foundation. Cut for the 14×12 brood box.Premium British Standard wired foundation cut to the full 14×12 depth for use in National 14×12 deep brood frames. Embedded wire reinforces the larger comb sheet, keeping it stable under the substantial weight of a deep brood pattern, pollen stores, and winter reserves. Full 14×12 depth — the correct size for deep brood framesStandard deep foundation is too short for a 14×12 frame. This foundation is cut to the full depth, so bees can draw comb across the entire frame surface. Embedded wire — essential at 14×12 depthA deeper frame means a larger, heavier comb. The embedded wire prevents sagging and buckling under the extra load — more important here than in a standard brood frame. Premium BS standard — consistent cell sizeManufactured to British Standard specifications. Bees draw the comb cleanly and evenly, giving you straight, well-formed deep frames that are easy to inspect and manage.
