iSPECLE Expandable Sink Drainer, 12.4 to 17.1 Inches, Square Corner Frame, 39 lb Rated

Fit rules here are stricter than usual and worth reading twice. The basin's internal length must fall between 12.4 and 18.7 inches, and its internal width, measured across the flat portion rather than around the curve, must exceed 12.8 inches; deeply curved corners rule this rack out. Leave roughly 0.6 inches of clearance between tap hole and basin edge so the frame can hang securely. The body measures 12.4 to 17.1 inches long, 12.8 inches wide and 4.1 inches tall.

Square corners are the point of the design: they match zero-radius modern basins and waste none of the opening. Widened flat iron bars replace the usual round wire, which is why ceramic plates stand upright without the frame bowing, and the rack carries a rated 39 pounds. Two things stop it collapsing mid-wash. A screw lock holds the chosen length so the frame cannot retract, and L-shaped handles drop through 90 degrees to grip both basin wall and worktop edge. Soft rubber feet finish the underside. Weight is 1.91 pounds.
