When to use: Use these sheets when assembling or replacing deep brood frames for a standard deep hive setup.
How It Works
Each foundation sheet snaps into a 9-1/8" grooved top bar frame and is then placed into a 9-5/8" deep brood box.
- Triple wax coated to help encourage bee acceptance
- Food grade plastic construction for durability
- Impervious to wax moth damage
- Works with manual and automatic uncapping equipment
