I claim the ornamental design for a pipe trench side panel elbow, as shown and described.

FIG. 1 is a front perspective view showing top, left and right sides of my new design, with intermediate regions of the perpendicular legs of the panel that form no part of the claimed design being shown by broken lines, indicating that the legs which form left and right sides of the panel are of indefinite length;

FIG. 2 is a rear perspective view thereof;

FIG. 3 is a top view thereof;

FIG. 4 is a bottom view thereof:

FIG. 5 is a left side elevational view thereof; and,

FIG. 6 is a right side elevational view thereof.

The design relates to short opposite end regions and to a right angle central region of a side panel used in forming pipe trench elbow and tee sections. Each of the perpendicular legs of the panel are of indefinite length.

All subject matter depicted by broken lines is environmental, is provided for merely for illustrative purposes, and forms no part of the claimed design.

Chrien, David J.
