(57) A reinforced channel (104), for use in an extension arm that mounts a device to a
support, comprises a U-shaped body (130) with a pair of spaced apart sidewalls (182)
and a bottom wall (180) therebetween, each sidewall having an upper edge opposing
the bottom wall. A rib assembly within the body between the sidewalls overlies the
bottom wall, and comprises a plurality of first ribs (400) projecting upwardly from
the bottom wall transversely from one of the sidewalls to the other of the sidewalls
and a plurality of second ribs (402) projecting upwardly from the bottom wall at an
oblique angle to the sidewalls. The rib assembly extends from the bottom wall to a
location below the upper edge of each sidewall and forms, within the body, a passageway
extending from its first end to its second end between the upper edge of each sidewall
and the rib assembly.
