ABSTRACT:
A profile for the coupling of adjoining channel members comprises a front wall for extending perpendicularly from a wall of the channel member, a back wall extending at least partially parallel to the front wall, a front flange connected to the front wall, a back flange connected to the back wall and a deformable sealing material in the space between the front wall, the back wall and the flanges. The profile is constructed by folding a strip of material along parallel fold lines. A deformable sealing material is applied to the strip, and when the strip is folded, the sealing material is deformed so as to fill a substantial portion of the space between the front wall, the back wall, the front flange and the back flange of the profile.
