Colingmill 2-Pack 10-Frame Inner Covers with Aluminum Entrance Feeders — Fir Wood Insulated, Perforated Ventilation

Colingmill's 2-pack inner covers with matching entrance feeders are purpose-built inserts for 10-frame hives that improve ventilation, offer insulation, and make feeding simpler.

Whether you're expanding a backyard apiary or replacing worn components, these inner covers and aluminum entrance feeders give beekeepers a reliable, weather-resistant set that fits standard 10-frame boxes. The pair combines a fir-wood inner cover with a pre-cut feeding hole and two slip-in aluminum feeders to streamline syrup or water provisioning while helping airflow management inside the hive.

How do these inner covers help hive ventilation and temperature control?

The inner cover is constructed to promote steady air movement while offering a layer of insulation beneath the outer cover. Proper airflow reduces condensation and helps bees regulate the cluster without exposing them to drafts. The wood thickness and cutouts are balanced to maintain internal hive stability across seasons.

• Perforated design allows fresh air circulation without large cold drafts.
• Fir wood provides insulating properties to buffer temperature swings.
• Fits between top box and outer cover for a secure seal and moderated exchange.

What makes the entrance feeders easy and safe to use?

The set includes two low-profile aluminum entrance feeders sized to match the cover's feeding hole, letting you offer supplemental syrup or medicated feeds without removing the top cover. Their compact shape minimizes spilled syrup while giving bees access at the hive entrance area.

• Aluminum construction resists corrosion and is simple to clean.
• Slip-fit design secures into the feeding hole to prevent jostling or tipping.
• Small opening size reduces robbing risk while allowing worker access.

Will these components fit my existing 10-frame hive equipment?

The inner cover measures approximately 19.88 x 16.34 x 0.98 inches and is sized for standard 10-frame American hives. The feeders measure about 2.87 x 0.59 inches and align with common feeding-hole dimensions. These dimensions make installation straightforward and compatible with most 10-frame setups.

• Inner cover dimensions match typical 10-frame box openings.
• Entrance feeders sized to fit the included feeding hole snugly.
• Designed to sit naturally under the outer cover without modifications.

How durable and low-maintenance are these hive accessories?

Materials were selected for weather resistance and longevity: the inner cover uses fir wood known for exterior durability, while the feeders are aluminum for rust resistance. Routine cleaning and seasonal inspections keep the parts functional for years, reducing the need for frequent replacements.

• Fir wood body stands up to outdoor conditions when properly sheltered.
• Aluminum feeders do not easily corrode and clean with warm water.
• Simple design means fewer crevices for debris or pests to accumulate.

Who this is for: Beekeepers who run 10-frame Langstroth-style hives and want a practical, ready-to-use pair of inner covers with feeders. This kit suits newcomers seeking an easy feeding method and experienced apiarists replacing worn components with durable, weather-resistant parts.
