Newly designed aluminum dog crates Take everything you love about Rock Creek Crates to the next level. We’ve listened to your feedback and improved our heavy-duty dog kennel options while staying true to what sets us apart: our lightweight aluminum crate frames built for strength, structure, and safety. We’ve added an XXL size for your larger companions, and designed a fresh lineup of crate colors, which you can select from for no additional cost. Our escape-proof dog crates still come with a 10-year warranty and are the only crash tested aluminum dog crates – plus, all our crates ship fully assembled.
