- Perfect fit for most sinks: Over Sink Dish Drying Rack measures 20.5 x 13.8 inches, suitable for RVs, campers, and homes. Not suitable for farm sinks with uneven sides. It is designed for sinks with a shorter side not exceeding 19.5 inches in width. Before purchasing, measure your sink to ensure a proper fit. - Robust stainless steel construction: Made from food-grade 304 stainless steel, the rack is strong and sturdy and can support up to 33 lbs without bending. To extend its life, clean and dry the rack after each use. - Space-saving and portable design: The foldable, rolling design unfolds over the sink when needed and stores away in a drawer or locker when not in use. It saves counter space compared with bulky wire shelves or dish drain baskets, making it ideal for small countertops, travel trailers, and RVs. - Versatile functionality: Use as a dish drainer for air-drying bowls, pans, glasses, plates, and cutlery. Also works as a vegetable colander for washing fruits and vegetables, a non-slip trivet for hot pots and bakeware, and a practical kitchen sink accessory such as a sink caddy, sink cover, camping sink mat, sponge holder, or over-the-sink colander. - Use scenarios: 1) In a small kitchen or RV, unfold over the sink to air-dry dishes while keeping counters clear. 2) Rinse produce in the sink and drain using the rack as a colander. 3) Place hot pots on the rack to protect countertops as a non-slip trivet.
