This over-the-sink dish drainer drying rack is made of advanced stainless steel, including the main shelf and all accessories, offering a stylish, sturdy, smooth, corrosion-resistant, and rust-resistant build that is made to last and easy to clean. The heavy-duty metal shelf can hold up to 200 lbs and stays stable without leaning forward, with an anti-slip suction cup at the bottom for reinforcement stability. The adjustable frame fits a wide range of sink sizes and layouts, ideal for both single and double basin sinks, with a minimum width of 20.9" and a maximum width of 37.4", so you can freely adjust the length according to your needs. Its three-tier design efficiently utilizes vertical space and frees up 80% of your countertop, with ample capacity for oversized plates, bowls, and basins. Accessories include a knife holder, storage basket, cutlery holder, cutting board rack, cup hanging, hook up, and paper holder, all made of stainless steel. Before choosing, measure three values: sink width ≤37 in, faucet height ≤17 in, and cabinet-bottom-to-countertop height ≥39 in.
