Acorn Plastic Foundation

Acorn plastic foundation gives bees a strong, ready-to-draw comb base that won't bow, warp, or blow out in the extractor. Each one-piece sheet is precision-molded with a natural honeycomb cell pattern and finished with a heavy wax coating, so bees accept it quickly and build straight, even comb. Made in the USA, this Acorn plastic foundation is a durable, low-maintenance alternative to wax sheets for both brood and honey frames. Features One-piece, super-rigid sheet — resists bowing and warping for flat, stable comb. Precision-molded cell pattern — mimics natural honeycomb so bees draw it out readily. Heavy wax coating — a generous coat of beeswax encourages faster acceptance and comb building. Breakaway communication hole — pop it out to let bees move between frames, or leave it intact. Made in the USA — manufactured in California. Two sizes, two colors — Deep (9-1/8") and Medium (6-1/4"), in white or black. How it works The foundation snaps into a standard grooved wooden Langstroth frame and gives bees a centered guide to build on. The heavy wax coat is the part bees respond to — it smells and feels like comb they would build themselves, so they draw it out faster than bare plastic. Once drawn, the rigid plastic core stands up to repeated extraction without the blowouts you can get with wired wax.

Pick your color: White is the classic look and shows off honey and comb; black makes pale eggs and young larvae much easier to spot during inspections.

Use deep (9-1/8") foundation in brood boxes and medium (6-1/4") in honey supers, matching the depth of your woodenware. Why choose black over white? Black foundation makes it far easier to see eggs and young larvae against the dark background during brood inspections. White is the traditional choice and shows comb and honey nicely.

How it works

The foundation snaps into a standard grooved wooden Langstroth frame and gives bees a centered guide to build on. The heavy wax coat is the part bees respond to — it smells and feels like comb they would build themselves, so they draw it out faster than bare plastic. Once drawn, the rigid plastic core stands up to repeated extraction without the blowouts you can get with wired wax.
