The triangular design can efficiently utilize the corner space of the sink, without occupying too much countertop area and without affecting the cleaning of large kitchenware. The bottom of the triangular sink drain rack is 16 in. long and the sides are 9 in. long. The main body is made of 9 rust-proof stainless steel pipes embedded in silicone, combined with anti-slip silicone pads. It is sturdy, waterproof and has a longer service life than plastic sponge racks. The drain rack is of a roll-up structure and can be folded and stored under the sink or in the cabinet. When unfolded, it has multiple uses, such as holding sponges, glassware, etc., or serving as a fruit and vegetable drying rack, a thawing pad and a heat insulation pad. The silicone edges can be cut as needed and will not scratch the countertop when placed. The overall load-bearing capacity is 11 lbs. (approximately 5 kg). It can be cleaned without disassembly, either by rinsing directly or by putting it in the dishwasher. It is not prone to food residue and is suitable for most standard kitchen sinks.
