Patent ID: 7955027

Claim:
A link, for insertion between a first channel and a second channel that are configured to be connected to each other to form a linear conduit in the absence of the link, the first channel having an outwardly extending first flange on a first terminal end of the first channel, the first flange having opposite surfaces that are parallel with each other, the second channel defining a first slot at a second terminal end of the second channel, the first slot having opposing surfaces that are parallel with each other and separated by a first width, the first flange being configured to be inserted into and mate with the first slot to form a substantially linear connection between the first and second channels, the link comprising: an outwardly extending second flange on a third terminal end of the link, the second flange having opposite surfaces that are parallel with each other, and being configured to be inserted and mate with the first slot of the second channel to form a connection between the link and the second channel; and a second slot defined in a fourth terminal end of the link, the second slot having opposing surfaces configured to receive the first flange of the first channel, the opposing surfaces being spaced apart in relation to the first flange such that, when the first flange is inserted into the second slot, a horizontal gap is formed between the opposite surfaces of the first flange and the opposing surfaces of the second slot that is sufficient to allow the second channel to be rotated horizontally in relation to the first channel by an offset angle to the first channel that is greater than 1 . 5 degrees.
