Corner connector

A corner connector device comprising:

• (A) an outside connector component having a length and, when viewed in cross-section
• (a) a first leg and a second leg, the first leg integrally connected to the second leg along a lengthwise seam and forming a channel, the first and second legs each having an inside surface oriented relative to one another at an angle W of less than 180 degrees and each having an outside surface oriented relative to one another at an angle X of more than 180 degrees, and
• (b) an outside connector extending lengthwise along the outside connector component parallel to the seam and projecting from one of the outside surfaces;
• and
• (B) an inside connector component having a length and, when viewed in cross section
• (a) a third leg and a fourth leg, the third leg integrally connected to the fourth leg along a lengthwise seam and forming a channel, the third and fourth legs each having an inside surface oriented relative to one another at an angle Y of less than 180 degrees and each having an outside surface oriented relative to one another at an angle Z of more than 180 degrees, and
• (b) an inside connector extending lengthwise along the inside connector component parallel to the seam and projecting from one of the inside surfaces,
• wherein the inside and outside connectors can be lengthwise selectively connected to and disconnected from one another with confronting parts of the outside surfaces of the outside connector component and inside surfaces of the inside connector component spaced a distance from one another.
