Abstract
Abstract An extruded aluminum support post has a unique configuration to enable various elements to be readily secured thereto for support thereby. One form of the unique configuration has four recesses disposed 90* from each other with a threaded groove in the bottom wall of each recess to form a first set of threaded grooves extending for the length of the post. Each of the side walls of each recess forms a bottom wall of a threaded groove forming a second set of threaded grooves with the two threaded grooves adjacent each recess being disposed perpendicular to the threaded groove forming the bottom wall of the recess and having their mouths open away from the recess. A second form has a circular post with a first set of threaded grooves disposed at a lesser radius from the longitudinal axis of the post than a second set of threaded grooves, which are disposed between each adjacent pair of the first set of the threaded grooves.

Claim 1
Independent Claim
306 words
A longitudinal support post having: a plurality of longitudinal recesses extending for the length of said post and equally angularly spaced from each other; each of said recesses including a bottom wall and a pair of side walls, each of said side walls extending from said bottom wall in a direction away from the longitudinal axis of said post; each of said recesses having a threaded longitudinal groove in its bottom wall to form a first set of threaded grooves; each of said threaded grooves of said first set extending for the length of said post; each of said threaded grooves of said first set being disposed the same distance from the longitudinal axis of said post; said side walls of each of said recesses being spaced further apart from each other than the mouth of said threaded groove in said bottom wall of said recess; a second set of threaded longitudinal grooves extending for the length of said post; each of said threaded grooves of said second set being disposed the same distance from the longitudinal axis of said post; each of said threaded grooves of said second set being disposed a greater distance from the longitudinal axis of said post than each of said threaded grooves of said first set; said second set of threaded grooves having two threaded grooves between each adjacent pair of said recesses; one of said two threaded grooves of said second set between the adjacent pair of said recesses having its bottom wall formed by one of said side walls of one of the adjacent pair of said recesses; and the other of said two threaded grooves of saId second set between the adjacent pair of said recesses having its bottom wall formed by one of said side walls of the other of the adjacent pair of said recesses.
Claim 2
Dependent Claim
