Performance over the sink dish strainer is compatible and flexible to accommodate most sink sizes. The steel bars can shift and move due to flexibility. The kitchen rinse basket shelf is made of stainless steel and the plastic-coated wire construction is sturdy to hold stoneware plates securely and protects dishes and sinks from scratches. Just rinse vegetables and fruit and set them on the rack so water drips directly into the sink, not on your counters. This rack is also designed like it has a container inside so you would have a bigger space.
