## Abstract

A dual sided extrusion, where one side has a different shape than the other side, and the extrusion is intended to be used in different orientations depending on the application.

## Claims

### Claim 1

A method, comprising:
first using a structural extrusion in a first direction hanging from a ceiling where an I-beam shaped portion faces down and holds a load; and
second using the same structural extrusion in a second direction mounted in a floor, where an open cavity faces up and holds a load.

### Claim 2 (depends on 1)

A method as in claim 1, wherein said first using comprises mounting from the open cavity, and where said second using comprises mounting from the I-beam portion.

### Claim 3 (depends on 1)

A method as in claim 1, wherein said first using comprises using a captive nut, which held within said open cavity between sidewalls of said cavity portion, in a way that prevents said nut from rotating inside said cavity portion.

### Claim 4 (depends on 1)

A method as in claim 1, further comprising using the same clamp to hold said extrusion in said first direction and in said second direction.
