6 Best Foundationless Frames For Natural Comb That Prevent Cross-Comb
Discover foundationless frames with built-in guides for straight, natural comb. We review top designs that prevent cross-comb for easier hive inspections.
You crack open a hive, expecting neat rows of honeycomb, but instead, you find a chaotic mess of comb built sideways, welding three frames into one immovable block. This is the dreaded cross-comb, a common fear that keeps many beekeepers from trying foundationless beekeeping. But letting bees build their own natural comb is rewarding, and with the right frame, it’s far more manageable than you think.

The Basics of Foundationless Beekeeping
Foundationless beekeeping is exactly what it sounds like: you give the bees an empty frame and let them build their comb from scratch, without a pre-printed wax or plastic foundation sheet to guide them. The bees build cells sized to their own needs, which can be beneficial for colony health. It also means the wax is pure and new, perfect if you plan to harvest cut comb honey or render your own beeswax.
The challenge, of course, is convincing the bees to build straight. Without a guide, they will often build comb that curves across multiple frames, making inspections impossible without destroying their work. This is why the design of the frame’s top bar is so critical.
A good foundationless frame provides a clear, sharp guide along the underside of the top bar. This "starting line" encourages the bees to draw their comb straight down, following the path of least resistance. The quality of this guide is the single most important factor in preventing cross-comb.
Mann Lake Wedge Top Bar: Simple & Effective
The wedge top bar is a classic for a reason. This wooden frame features a removable wedge-shaped piece of wood that fits into a groove on the top bar. You simply pop the wedge out, place a starter strip of wax foundation in the groove, and nail the wedge back in place to hold it securely.
This design is incredibly effective. The starter strip gives the bees a substantial guide to follow, and the wedge holds it tighter than almost any other method. It’s a bit more work during assembly, as you have to nail in the wedge on every frame, but that small effort pays off in beautifully straight comb.
For a beekeeper who wants a reliable, time-tested method, the wedge top bar is a fantastic choice. It combines the natural appeal of a wooden frame with a nearly foolproof system for getting straight comb. It’s the standard against which other foundationless frames are often measured.
Dadant Grooved Top Bar for Easy Wax Guides
If the wedge top bar sounds like too much fiddling, the grooved top bar is your answer. Instead of a removable wedge, this frame has a simple channel, or groove, cut directly into the center of the top bar’s underside. This design offers versatility and speed.
Your main options for creating a guide here are simple and quick. You can either press a starter strip of wax into the groove or, even easier, turn the frame upside down and run a line of melted beeswax down the channel. Some beekeepers even just glue a popsicle stick or a wooden coffee stirrer into the groove as a physical guide.
The tradeoff is a slightly less secure guide compared to the wedge style, especially if you’re just pressing in a wax strip. However, for speed and ease of assembly, the grooved top bar is hard to beat. It’s an excellent, no-fuss option for beekeepers who build a lot of frames and want to get the job done efficiently.
Betterbee Select Frames: Premium Wood Quality
Sometimes the "best" feature isn’t a fancy design, but simply superior craftsmanship. Betterbee is known for its high-quality woodenware, and their select-grade frames are a prime example. They are precisely milled from high-grade pine, meaning the pieces fit together tightly and squarely.
Why does this matter for foundationless beekeeping? A frame that is perfectly square and free of warping provides a true, straight structure for the bees to build on. A poorly made, twisted frame can encourage crooked comb before the bees even start drawing wax. Investing in quality frames means they last longer and provide a better canvas for your bees.
While Betterbee offers standard wedge and grooved top bars, choosing their select grade is a decision to invest in the fundamental quality of your equipment. For the beekeeper who sees their hives as a long-term investment, starting with the straightest, most durable wooden frames is a smart move that prevents future headaches.
Acorn One-Piece Plastic Frames for Durability
Get 10 durable, medium-sized black plastic frames for your beehive. Made in the USA and coated with 100% real beeswax to encourage acceptance by your bees.
For beekeepers who prioritize durability and ease of use, one-piece plastic frames are a compelling option. The Acorn frame is a popular choice, molded as a single, solid unit. There is no assembly required; you just take it out of the box and it’s ready for the hive—almost.
The key to success with any plastic frame is wax. Bees are reluctant to build on bare plastic, so these frames must be heavily coated in melted beeswax. You can dip them or use a paint roller to apply a thick, even coat. The underside of the top bar is shaped into a sharp edge to serve as a built-in guide.
The benefits are significant. These frames are nearly indestructible, won’t ever warp, and are impervious to wax moths. They are also easy to clean by scraping them down to the plastic. The primary tradeoff is the unnatural material and the upfront work of waxing them, but their longevity and strength make them a very practical choice.
Bee-Minded Inverted Top Bar: A Unique Design
The Bee-Minded frame offers a clever, low-effort solution to creating a guide. Instead of a groove or wedge, the underside of the top bar is milled into a prominent, inverted "V" shape that runs the length of the frame. This sharp, wooden peak creates an unmistakable starting line for the bees.
This design is brilliant in its simplicity. You don’t need to add wax strips, melt beeswax, or glue in guides. The guide is an integral part of the frame itself. This saves a huge amount of time and removes a tedious step from your frame-building process.
For beekeepers committed to a completely foundationless and wax-free guide system, this is arguably the best design available. It relies on the bees’ natural instincts to follow a sharp edge. The only consideration is that the guide isn’t quite as "loud" as a wax starter strip, so ensuring your hive is perfectly level remains critically important.
Pierco Frames: A Heavy-Duty Plastic Option
Similar to Acorn, Pierco offers a one-piece plastic foundationless frame designed for maximum strength. These frames are known for being exceptionally rigid and durable, making them a favorite among beekeepers who are tough on their equipment, especially during honey extraction.
Like all plastic frames, Pierco frames require a heavy coating of beeswax to encourage the bees to build on them. They feature a molded guide along the top bar, but the real selling point is their sheer toughness. A fully drawn-out comb of honey is heavy, and these frames can handle the stress of a high-speed extractor without breaking or bowing.
Choosing Pierco is a decision based on prioritizing strength and longevity above all else. If you plan on extracting honey and want a frame that will last for decades with minimal maintenance, this is a top contender. It’s a workhorse frame built for utility.
Installing Guides and Managing Your New Frames
Choosing a great frame is only half the battle; management is the other half. Regardless of the frame you choose, a few principles will ensure your success with natural comb. First, always keep your hive perfectly level. A tilted hive will encourage bees to build their comb at an angle, leading to cross-comb.
Second, introduce new foundationless frames between already drawn-out combs. This "checkerboarding" technique creates straight "walls" on either side of the empty frame, leaving the bees little choice but to build straight down the middle. Avoid placing a whole box of empty foundationless frames on a hive at once, as that’s an open invitation for creative comb architecture.
Finally, inspect new foundationless frames frequently—every few days if possible. If you see the bees starting to go crooked, you can gently push the new, soft comb back into alignment. Correcting a small mistake early is much easier than fixing a big one later.
Ultimately, the best foundationless frame is the one that aligns with your beekeeping goals, whether that’s the simplicity of a wooden guide, the durability of plastic, or the reliability of a classic wedge. By pairing a quality frame with mindful management, you can enjoy the benefits of natural comb without the mess. The straight, beautiful combs your bees will build are well worth the effort.
