Deep 9 1/8 Inch Langstroth Frame, Wedged Top / Split Bottom with Holes

Our Deep 9 1/8 Inch Langstroth Frames are designed for precision and practicality — meeting the natural needs of your bees and your needs as a beekeeper. Bees maintain a specific bee space between combs, and these frames maintain that spacing automatically when placed side by side, so bees build comb efficiently and you get easy access for inspection.

Detailed Description

Each frame comes as a four-piece set — a wedged top bar, split bottom bar, and two sidebars with holes — that fit together securely with glue, nails, or staples. Once assembled, the frame gives bees a reliable structure to draw out comb, and gives you an easy way to inspect, extract, and manage the colony.

These deep frames are most commonly used in brood boxes, where the queen lays eggs and the colony maintains its population through the year. The deeper frame gives the queen more continuous laying space and ample area for brood and stored resources.

The wedged top bar has a removable wedge strip that holds wired beeswax foundation securely in place, while the split bottom bar lets the foundation rest in the groove, preventing bowing or warping over time.

The sidebars include pre-drilled holes for additional horizontal support wires, which strengthen the foundation and help prevent comb collapse when frames are full of brood or heavy honey stores.

Each frame is sold unassembled. Assembly is straightforward with standard tools and good-quality wood glue, and proper assembly will keep your frames holding up season after season without separating inside the hive.

These frames fit standard Langstroth deep boxes and are compatible with 100% beeswax deep foundation with wires.
