1.Stable and Adjustable: The drain rack is designed with 18 extendable stainless steel pipes, adjustable from 13.19' to 20.27'(33.5cm-51.5cm), to fit a wider range of sink sizes (Please confirm sink dimensions before purchase). The compression design at the extension point ensures a stable support and prevents detachment. 2.Roll-Up Saving Space: If you live in an RV or a small apartment with limited kitchen space, a collapsible and extendable over the sink drying rack can be a great helper in your kitchen. When in use, you can fully extend it to organize your sink, and after using it, you can collapse it and store it in a cabinet or drawer, taking up no space at all. 3.Multiple Occasions: The dish drying rack can handle various kitchen tasks, such as filtering bowls, dishes, and pot covers, drying fruits and vegetables, placing frozen foods to thaw, and cooling hot pots and pans, keeping your kitchen more organized. 4.Premium Material: 304 stainless steel drain rack that is highly resistant to rust (recommended for dry water stains after use). The edges are securely wrapped with silicone to prevent peeling and anti-slip, ensuring smooth edges that won't hurt your hands.
