Solid bottom board 10F

Fixed-floor design — body nailed to the bottom

Unlike modern screened or detachable floors, on a fixed-floor bottom the brood box is nailed directly to the bottom board. The whole assembly gains rigidity and eliminates gaps, but bottom and body now move as one — to inspect underneath you flip the whole box. It’s old-school beekeeping: fewer parts, fewer replacements, and a markedly lower cost than a screened bottom with a removable tray.

Two sizes to match your hive

Langstroth / Dadant US (10 frames) — 51.5 × 43 × 5 cm
Removable landing board, not included in the measurements. The front extension comes off when you don’t need it, or to stack and ship with less wasted space.

Dadant Blatt (12 frames) — 55 × 43 × 5 cm
Built-in landing board, included in the measurements. The front extension is fixed from the factory, ready for foragers to land effortlessly.

⚠️ Important — entrance reducer not included

The bottom ships without an entrance reducer. The hive entrance is formed by the front gap between body and bottom, and you’ll need a separate part (metal, plastic or angled) to regulate it across the season: wide open in heavy nectar flows, narrowed for wintering or against Asian hornet pressure. You’ll find three compatible models below in accessories — long metal entrance reducer (the standard, by far the most common), anti-hornet entrance reducer (same width, calibrated slot that filters hornets out) and angled two-position entrance reducer (open/closed, useful for full winter closure).

Solid bottom, no mesh

It’s a solid bottom with no mesh or removable tray — this is not a screened bottom. You won’t be able to monitor natural varroa drop on a sticky board, and underfloor ventilation in hot climates is barely there. In exchange: simplicity, structural durability and a markedly lower price. Built for beekeepers running fixed-floor management who don’t rely on drop-board monitoring, or as a quick replacement when an old bottom gives up while the body is still sound.
