The Spectrum Silicone Sink Strainer Set of 2 catches food scraps at the drain before they cause clogs. Each strainer measures 4.5 inches in diameter and 1.5 inches deep. It sits securely in standard kitchen and utility sink drains. The drainage openings trap fine residue and larger scraps while keeping water flowing. Flexible silicone lets you lift the strainer out with one hand and empty it straight into the trash. Smooth edges stay comfortable to handle with wet or soapy fingers. The silicone will not scratch stainless steel, porcelain or composite drains. It holds up to hot water, grease and soap without cracking or stiffening. Clean it in the dishwasher, or rinse it and flex it to release trapped debris. Use the pair in a double sink or keep one as a spare.
