Medium 6 1/4-Inch Frame, Grooved Top / Grooved Bottom With Double Wax Foundation

Our Medium 6 1/4-Inch Langstroth Frames are crafted for durability, precision, and bee-friendliness. Each frame is built to maintain the ideal “bee space” between combs inside the hive — giving your bees exactly the room they prefer to work while keeping management easy for the beekeeper. These frames are designed to fit perfectly into standard medium boxes, allowing smooth removal and inspection while minimizing comb damage.

Key Features and Benefits

• Standard medium depth: 6 1/4-inch frame size for honey supers and medium hive bodies.
• 5-piece construction: Includes top bar, bottom bar, two sidebars, and a sheet of medium foundation.
• Double beeswax coating: Encourages faster, more even comb building.
• Grooved top and bottom bars: Snap-in design allows foundation installation without tools.
• Available assembled or unassembled: Simple to build with basic hand tools.
• Bulk shipping: Orders of 1,260 or more assembled frames ship via freight pallet.

Detailed Description

Each Medium 6 1/4-Inch Frame includes five parts — a top bar, bottom bar, two sidebars, and a medium foundation sheet — that fit securely together using wood glue, nails, or staples. The snap-in foundation easily slides into grooves on both the top and bottom bars, locking firmly in place without the need for wedges or tools.

Medium frames are most commonly used in honey supers, where bees store surplus honey that can be harvested. Increasingly, some beekeepers also use medium-depth boxes for the entire hive to standardize equipment.

In 2015, we switched from thinly coated foundation to a double-coated American beeswax foundation after testing how bees responded. The heavier wax coating significantly improves comb acceptance and building speed — a clear improvement noticed by both our bees and our customers.

These frames are sold unassembled or assembled, with assembled options built using strong adhesives and nails to ensure longevity and stability. For large orders, bulk quantities of 1,260 or more assembled frames are shipped by freight on a pallet for secure delivery.
