Bases

A shallow base is set into the pavement structure to carry an in-pavement fixture, in 8-inch and 12-inch sizes; the 12-inch base also takes an 8-inch fixture through the standard 12-to-8 adapter ring, so one anchorage serves both sizes. The extruded aluminum body uses an equal-strength section with internal ribs and has passed the FAA loading sub-test, so aircraft wheels and snow-clearing plant crossing the rim do not distort it; cable can enter from the bottom or the side, the secondary cable comes in through a metal waterproof connector that keeps the can dry, and stainless thread inserts protect the screw holes through routine removal. The same range includes 12-inch deep bases in aluminum and in stainless steel, tall enough to hold the isolation transformer and single-lamp controller beneath the light with no separate transformer pit, plus 11-inch, adjustable and cast shallow bases.
