     DETAILED DESCRIPTION OF THE INVENTION 
       [0023]    A post mounting and stabilization system  10  of the invention can be seen in  FIG. 1  of the drawings positioned on a hollow mounting post mount  11  for securing to a foundation via an attachment plate  12  shown broken away. A top rail stabilizer  13 , best seen in  FIGS. 1 ,  2  and  3  of the drawings has a generally square tapered sleeve base  14  with opposing pairs of independent extending engagement finger plates  15 ,  16 ,  17  and  18 . The corresponding respective finger plate pairs are integral to the base  14  with corresponding spaced adjacent elongated generally parallel edges  15 B and  18 A,  18 B and  17 B,  17 A and  16 B and  16 A and  15 A defining multiple longitudinal tapered openings  19 - 22  between the respective finger plates  15 ,  16 ,  17  and  18 . 
         [0024]    Each of the finger plates is of a tapered dimensional thickness from its respective base  15 C,  16 C,  17 C and  18 C to its free end edge  15 D,  16 D,  17 D and  18 D, best seen in  FIGS. 2 and 3  of the drawings. The taper affords the finger plate&#39;s displacement under applied force outwardly and opposing finger plate pairs  15  and  17  and  16  and  18  indicated by directional arrows A in  FIGS. 2 and 3  of the drawings. 
         [0025]    The sleeve base  14  has tapered reinforcement ribs  14 A on each of its exterior surfaces  14 B which extend and engage with the hereinbefore described finger plates as illustrated in  FIG. 3  of the drawings with an interior uniform pass through dimension to accommodate the insertion of the top rail stabilizer  13  onto the mounting post  11  as seen in  FIG. 1  of the drawings and broken lines in  FIG. 3  of the drawings. 
         [0026]    An expander wedge fitting  23  can be seen in  FIGS. 4-7  and  FIG. 1  of the drawings in solid and broken lines of a one piece generally square tubular configuration having interconnecting upstanding sidewalls  24 ,  25 ,  26  and  27 , each within integral right angularly inwardly extending flanges  24 A,  25 A,  26 A and  27 A respectively, best seen in  FIGS. 4 and 6  of the drawings. The flanges define a central opening at  28  for registration with the mounting post  11 . 
         [0027]    The adjoining sidewalls define respective curved corners  29 , each of which has a finger edge engagement contoured lug  30  extending outwardly therefrom in angular relation to the respective adjoining sidewalls planar surfaces. The lugs  30  have a contoured bottom surface  30 A and transitional oppositely disposed side engagement surfaces  31 A,  31 B as will be described in greater detail hereinafter. 
         [0028]    Referring now to  FIG. 1  of the drawings, it will be seen that the post mount stabilizing system  10  is illustrated in use wherein the wedge fitting  23  is shown in integral mounting post  11  engagement position in engaging deployed position on the mounting post  11  and in broken lines prior to insertion on the mounting post  11  within the finger plates  15 ,  16 ,  17 ,  18 . 
         [0029]    In sequential operational deployment steps, the mounting post  11  is secured to the chosen foundation by multiple fasteners, not shown, extending through corresponding aligned apertures A in the attachment plate  12 , as will be understood by those skilled in the art. The post stabilizer  13  is inserted onto the mounting post  11  at its desired location and secured in place by fasteners F. The expandable wedge fitting  23  is prepositioned on the support mounting post  11  acting as a sizing stabilizer to effectively adjust the post stabilizer  13  to engagement with the finished post FP, shown in broken lines in a typical post rail installation which will be positioned there over. The expander wedge fitting  23  shown in broken lines prior to use as inserted is driven down the mounting post  11  by applying external force against the fittings interlocking flanges  24 A,  25 A,  26 A and  27 A in this example shown in solid lines wherein the multiple contoured lugs  30  are correspondingly slidably engaged within the respective tapered openings  19 - 22  between the finger plates forcing the respective finger plates  15 - 18  progressively outwardly in translateral forced applied orientation to one another so as to engage the respective applied inner surfaces of the finished post FP securing and stabilizing same in place. 
         [0030]    It will be apparent that the post stabilizer  13  as inserted and expanded as hereinbefore described will provide the adjustable size stabilization to accommodate different dimensional finished post FP as required by the thickness of the post composition encountered within the industry. Additionally, the post stabilizer  13  provides for rail reinforcement bracket attachment, if required, in such applications including placement, multiple post stabilizers  13  on a single mount post  11  as will be understood by those skilled in the art. 
         [0031]    It will be evident that the post mounting and stabilization system  10 , hereinbefore described provides for a universal fit for a variety of dimensionally sized finished posts FP for use, as noted. 
         [0032]    It will thus be seen that a new and novel mounting post and stabilization system has been illustrated and described and it will be apparent to those skilled in the art that various changes and modification may be made thereto without departing from the spirit of the invention. Therefore I claim:

Summary:
A post mounting and stabilization assembly for securing hollow posts to a foundation surface. The mounting assembly provides for wedging retainment of a hollow post thereover by the progressive engagement and deployment of opposing finger pairs extending from an integral base by a sliding deployment wedge fitting there within.
