An evacuated-tube collector is secured to the rack by clamping the manifold and the tube's mounting rail to a frame, which has two or three rails that run parallel to the tubes. The collector is tilted by using legs bolted to the mounting rails and attached to the roof via a foot or to another stainless steel section that connects to the bottom end of the mounting rail to form a triangle.
Evacuated-tube collectors often need cross-bracing, seen here through and behind the tubes.
