These aluminum parts can be used across the top of an awning to provide additional support between rafters or primary support where no rafter will be used (use two #10 wood screws). A head rod pipe is installed into a sleeve and that pipe is secured to the building using this clamp.
If installing in cement use cement anchors and appropriate screws.
The correct pipe for the head rod is 1/2" EMT (Electrical Metallic Tubing).
