The ornamental design for a pair of escalator control boxes, as shown and described. |
|||||||||||||||||
FIG. 1 is a right perspective view of a pair of escalator control boxes showing our new design;
FIG. 2 is a left perspective view thereof.
Shaded areas comprise display and windows that contrast with the opaque portions of the escalator terminal. The broken lines show the environment, an escalator terminal, in which the pair of escalator control boxes are placed and form no part of the claimed design.
