8. In a blind latching system for enclosures having a closure element moveable between open and closed positions and a fixed element, the combination of a keeper sub-assembly adapted for attachment to said fixed element, a latch sub-assembly adapted for attachment to a surface of said closure element and including a latch positioned for cooperative latching action with said keeper sub-assembly and release means operatively positioned relative to said latch for unlatching said latch sub-assembly from said keeper sub-assembly, said keeper sub-assembly being provided with a bracket having at least one wall defining opposing inner and outer surfaces extending in a longitudinal direction and having an opening therein, a keeper pin projecting through said opening and means for aligning said keeper pin for movement of said keeper pin relative to said bracket along an x axis, a y axis and a z axis comprising a resilient housing defining outer and inner surfaces and having an opening therethrough receiving said keeper pin, with said inner surface of said housing engaging ad outer surface of said at least one wall.

9. An apparatus of claim 8, wherein said keeper pin comprises a generally elongated shaft including a threaded portion and said aligning means further comprises a retaining member positioned engaging said housing and spaced from said at least one wall of said bracket and with said retaining member including a threaded aperture for receiving said threaded portion of said generally elongated shaft.

10. An apparatus of claim 9, wherein said housing is comprised substantially of an elastomeric material.

11. An apparatus of claim 10, wherein said housing is generally square in configuration and said retaining member comprises a retaining nut.

12. An apparatus of claim 9, wherein said at least one wall of said bracket includes a perimeter defining at least two opposing sides, with said bracket further including first and second end walls attached to said at least two opposing sides of said at least one wall, respectively, with said first and second end walls being substantially transverse said inner and outer surfaces of said at least one wall defining a generally U-shaped bracket.

13. An apparatus of claim 12, wherein said first and second end walls of said bracket further comprise means positioned distal said attachment with said at least one wall for attaching said bracket to a panel.

14. An apparatus of claim 13, wherein said at least one wall of said bracket further comprise a perimeter having four sides, with said bracket further comprising third and fourth end walls attached to opposing sides of said at least one wall and positioned substantially transverse said inner and outer surfaces of said at least one wall of said bracket.

15. An apparatus of claim 9, wherein said at least one wall of said bracket defines a perimeter having at least one side, with said bracket further including a first end wall having a top and a bottom said top of said first end wall being attached to said at least one side and said first end wall being positioned substantially transverse said longitudinal axis of said at least one wall, wherein said bracket further includes a second wall attached to said bottom of said first end wall and positioned substantially parallel to said at least one wall, with said second wall defining four sides and having a hole therethrough co-axial with said hole through said at least one wall, wherein said first and third sides of said second wall are positioned opposite to each other and said second and fourth sides of said second wall are positioned opposite to each other, with said first side of said second wall being attached to said bottom of said first end wall, said second side of said second wall attached with a second end wall generally parallel to said first end wall, said third side of said second wall attached with a third end wall generally parallel to said first end wall, and said fourth side of said second wall being attached with a fourth end wall generally parallel to said first end wall, wherein a cavity is defined between said first end wall, said second end wall, said third end wall and said fourth end wall into which said housing and said retaining member are positioned.
