Super Shim 3 en 1

A hive shim is a spacer installed between hive components to create additional space inside a beehive. Beekeepers use hive shims for purposes such as fondant feeding, improving ventilation, adding upper entrances, and reducing moisture buildup. The 3-In-1 Super Shim® combines all three functions into a single modular design for Langstroth hives.

While not required, many beekeepers use an upper entrance to improve hive traffic and reduce congestion at the main entrance. During nectar flows, an upper entrance can provide foragers with a shorter route to honey supers, helping bees move nectar more efficiently throughout the hive.

Yes. A ventilation shim can improve airflow inside the hive by creating adjustable openings that allow excess heat and humidity to escape. Proper hive ventilation can help bees regulate temperature more effectively during hot weather and reduce moisture accumulation during cooler months.

Yes. Excess moisture inside a hive can lead to condensation, mold, and poor wintering conditions. A properly configured ventilation shim helps improve airflow and allows moisture to escape, creating a drier and healthier hive environment.

The 3-In-1 Super Shim® is designed to create ample space above the frames for fondant patties used during winter and early spring feeding. Capacity varies depending on the size and thickness of the fondant patty, but the shim provides sufficient clearance for most commercially available fondant products.

Bees may apply propolis to ventilation openings as part of their natural hive management behavior. However, we've found that if placed above the inner cover bee's tend to leave them untouched.

Yes. The 3-In-1 Super Shim® is commonly used above a queen excluder to provide an upper entrance for foraging bees. This configuration can improve access to honey supers while maintaining the benefit. On occasion, we've witnessed some burr comb built to bridge the gap between the queen excluder, however we don't think it's an issue.

No hive accessory can guarantee increased honey production. However, improved ventilation, reduced entrance congestion, and more efficient forager traffic may help colonies operate more efficiently during nectar flows, which can contribute to stronger honey-producing conditions.

Yes. The 3-In-1 Super Shim® can be used throughout the year. Many beekeepers use it as a ventilation shim during summer, an upper entrance during honey flows, and a fondant feeding shim during winter and early spring.

Yes. PETG is a durable, food-safe plastic commonly used in food containers and outdoor applications. It offers excellent resistance to moisture, UV exposure, and temperature fluctuations, making it a reliable material for long-term beekeeping equipment.

Bees may build burr comb in any extra space within a hive, especially during strong nectar flows. Proper placement and seasonal use help minimize burr comb, and any comb that is built can typically be removed during routine hive inspections if desired.
