Most listed tools are made of plastic: feeders use high-quality, non-toxic plastic, and excluders are made from flexible, corrosion-proof plastic.
The water feeder measures about 6 in × 5.25 in × 3.5 in. The queen excluder is listed at roughly 20 in (W) × 16.5 in (H).
The feeder has a transparent body so you can see water levels, and it holds about 16.91 oz, making it easy to tell when a refill is needed.
The queen excluders are sized to fit 10-frame Langstroth beehives.
Product listings note rust-resistant or corrosion-proof construction, so the tools are designed to resist corrosion over time.
Reported weights range from about 0.17 lb for the feeder to about 0.6 lb for the excluder; the feeder is described as lightweight and durable.
The excluder uses a grid with openings sized to let smaller worker bees pass while preventing the larger queen from moving through, keeping the brood chamber separate from the honey super.
