Mr. Peanut's Foldable Soft Sided Portable Pet Carrier Crate Mr. Peanut's Portable Pet Crate is re-designed with a lightweight (4-5lb), one click assembly patented aluminum frame. Oxford 600D Nylon Fabric is standard and a thick gauge tinted Teslin mesh is used to keep your pet calm, safe and secure. The soft and comfortable faux fleece padding is supported by a 1/4" plywood base insert for additional weight support unlike all other pet crates on the market. The crate uses aluminum expansion bars to fully maximize the interior space in the crate for pets that appreciate the extra roomy box like space in their pet house. This frame is easily assembled in seconds by just pushing the expansion bars outward, and then reversing to quickly collapse the crate to less than 4" of space for carrying or storage.
