Corner Piece For Mechanically Interlocking Frame Members

A corner piece for interconnecting frame members, comprising:

• a first plate member defining an inner face, an opposite outer face, a first side face, and an opposite second side face, the first plate member including a bolt-receiving bore extending between the inner face and the outer face of the first plate member along a first axis;
• and
• a second plate member operatively connected to the first plate member and defining an inner face, an outer face, a first side face, and an opposite second side face, the second plate member including a bolt-receiving bore extending between the inner face and the outer face thereof along a second axis;
• and
• a first lip extending along the outer face of first plate member and being defined by first and second sidewalls, the first sidewall being spaced from the first side face of the first plate member and the second sidewall being spaced from the second side face of the first plate member.
