Durable and Practical: The sink strainer holder is made of PP material and features a sector design for enhanced stability and long-term durability. No need to manually clean the drain strainer—simply lift the mesh bag and dispose of it. Suction Cup Design: The filter frame includes a suction cup for easy installation. Press the suction cup firmly against the edge of the kitchen sink to create a secure hold. The suction cup provides strong adhesion and can be easily removed or repositioned as needed. Easy to Install: Clean and dry the surface before installation. Attach the drain holder to the sink, press to expel air from the suction cup, and let it set for 12 hours. Hang the sink drain bag on the designated hook. Space Saver: The corner sink strainer set mounts neatly in the corner of your kitchen sink. Designed with a triangular shape to fit corner spaces, it saves space and does not interfere with regular sink use.
