Abstract
A clip is bolted to the wall at points along the rail to hold the rail on the wall. Each clip includes a rigid retainer and a curved springy spacer. The clip is bolted to the wall to force the spacer against the rail, to force the rail against the wall. The spacer is slightly flattened to hold the rail in place, but allows the rail to slide in the retainer, along the wall, as the wall settles, thus preventing compression forces in the rail between the clips.
