Abstract

The gutter section is used in support assemblies, using locking fork pieces, with strips on the outside. The bottom and sides are flat, inside and outside. These inner and outer faces are at a slight angle to each other to give a tapered section. A kink is left part of the way up each side. The relationship between the height of the side strips and the width of the bottom of the profile lies between 1.25 and 3.5. The angle of the thrust surfaces of the strips is between 75 and 85 degrees relative to the plan longitudinal of the profile.
