What is the ledge called where the frames hang inside the hive?

The correct term for the ledge where the frames hang inside the hive is known as the rabbet. In the context of beekeeping, the rabbet refers to a recessed area or groove cut into the hive body that provides a secure resting place for the frames. This design is essential for proper frame alignment and stability, allowing bees to build their comb and store honey effectively.

Understanding the function of the rabbet is key for beekeepers as it ensures that frames are easily accessible for management tasks such as inspections, honey harvesting, and maintaining the overall health of the hive. The other terms do not accurately describe this feature—shoulder refers to a different structural component, bridle is unrelated to frame support, and base typically denotes the bottom structure of the hive rather than the frame support.
