<p>A flase ceiling is suspended by hangers connectable to support rails. In the upper area, the support rail has a widened profile head, running continuously over its whole length, gripped by parts of the hanger. The head itself is also hood-shaped, and at the transition to the head each shank has an inward-formed step, providing a bearing face for the bent parts of the clamping spring, only slightly inclined to the base of the head.</p> |
