Juno® Trac-Master® T811-Series Uno open-back fixtures feature concentric gimbal rings that spring off the bottom edge of the chiseled monolith in a perfect example of “form follows function." The monolith cleverly conceals the integral transformer and remains perfectly aligned with the trac while the gimbal ring mechanisms are free to provide broad aiming capability. These unique low-voltage fixtures are available in white, black, or silver.
