HEIGHT AND AZIMUTH ADJUSTABLE CONTAINERS
An airport inset light adjustable alignment container set provides a light fixture and support for airport runway, taxiway, or other aircraft ground traffic areas and variable length extension means for rotatably adjusting height by plus or minus 0.4 millimeter or more and azimuth alignment by about plus or minus one degree or more. For previously installed, old airport inset lights, a variable length extension assembly of the present invention can be connected to a fixed connecting flange for rotatably adjusting the height and azimuth alignment of a conventional, prior art airport inset light, e.g., one which has been previously installed without the benefit of the present invention. An overlay protection plate protects against paving material entering the light fixture support during airport paving operations and locates the light fixture support after the airport paving operations have covered it. The overlay protection plate is firmly held bolt-free on the light fixture support, and the pavement cover is removed in substantially one piece.
