Buying Guide: Double Cup Basket Strainer Essentials
What to consider before buying
- Sink type and opening size: Cast iron, composite, and stainless steel sinks vary in diameter. Check flange size and cup depth to ensure a proper seal.
- Material durability: Stainless steel variants offer corrosion resistance and longevity. For heavy use, stainless with a robust cup is preferable.
- Open/close mechanism: Post baskets with spin-and-seal features simplify removal for cleaning. Consider ease of use if you frequently empty debris.
- Installation compatibility: Some models are OEM-specific. Verify your sink’s brand and model number when selecting an OEM replacement.
- Filtration and mesh: A double mesh can improve filtration for finer debris; if you have a disposal, ensure the mesh won’t clog easily.
- Size and flange: Larger flanges provide a more secure fit but require matching sink openings. Be sure to measure the drain opening.
