An awning system having miter connectors suitable for attaching to portions of T-slot tubing members is disclosed. The awning system can be shipped by conventional shipping mechanisms, does not require welding, and does not require a flat-bed truck for transport. Also, the awning system can then be assembled and installed on-site, rather than being shipped in a fully pre-assembled state. The awning system uses proprietary tubing members and (in most embodiments) a miter connector to form an awning frame.
