This durable leak proof replacement pan fits all 18 inch long folding metal dog crates offered by MidWest Homes for Pets. The replacement pan is compatible with the single door / double door iCrate and Contour dog crates (fits models 1518, 1518DD, and 818). The durable replacement pan is made with a flexible polypropylene plastic mixture which is odor resistant, easy to clean and stronger than other replacement pans that are made of ABS plastic. Additionally, our replacement pans are injection molded during the manufacturing process making them more flexible / durable than competitors who vacuum seal their pans during the manufacturing process. These leak proof pans are designed to easily slide in and out of the dog crate for easy cleaning in the event an accident occurs. Although these are made as replacement pans for our dog crates, many customers also use them as a multi-purpose tray as well. Our replacement pans have been used as a multi-purpose tray to hold wet or muddy shoes / boots, as a tray to place your pet's food / water bowl on, a tray to place your cat litter box on to help contain a potential mess, a portable puzzle piece holder, laundry, paint, gardening, cargo liner (our 42" pan fits most SUV / car trunks.) and etc.… We at MidWest Homes for Pets understand that your dog is a part of your family and that's why we ensure our products are manufactured with the highest quality control standards creating a safe home for your pet that you can feel confident with. MidWest Homes for Pets stands behind the quality of our products with our “MidWest Quality Guarantee” 1-Year Manufacturer's Warranty.
