Inside corner connector for structural framing members

A connector for channeled linear members, comprising:

• mutually perpendicular first and second elongated sections having a cross sectional shape in a direction perpendicular to the direction of elongation conforming to the interior cross sectional shape of a channel of the channeled linear member, the elongated sections having a pair of ends in the direction of elongation allowing introduction of the elongated sections to open ends of channels in channeled linear members;
• a diagonal brace disposed between the first and second elongated sections to lie substantially outside any channel into which either the first or second elongated sections may be introduced;
• a first one of each pair of ends being proximate to one another;
• an indented perimeter section to the diagonal brace between the proximate first ends allowing a linear member to be placed against the indented perimeter section perpendicular to the directions of elongation for both the first and second elongated sections;
• tap holes through the first and second elongated sections;
• and
• set screws positionable in the tap holes.

A frame comprising:

• at least a first pair of structural framing members, the structural framing members each having at least one T-slot running lengthwise along a major surface of the structural framing member;
• a connector for positioning the pair of structural framing members perpendicular to one another, each connector including a pair of guide sections, the guide sections being elongated and each having a cross sectional shapes perpendicular to the direction of elongation conforming to the interior shape of the T-slot;
• and
• a strut diagonally connected between the pair of guide sections holding the guide sections mutually perpendicular and coplaner.
