Abstract
A joint is formed by positioning a connector within channel members to be joined which has a rotatable eccentric with different length radii to engage the lateral edges of the channels, and rotation of the eccentric causes its longer length side to engage the channel edges first, bringing the channel members tightly together as they are fastened.

A joint comprising:
- (a) two lengths of grooved metal sections;
- (b) a connector having end portions insertable into a groove in each of said sections;
- (c) a cam on each of said connector end portions;
- and
