The ornamental design for an extender for sidewall of truck roof, as shown and described.
FIG. 1 is a rear perspective view of an extender for sidewall of truck roof for use on the right sidewall of a truck roof showing our new design, the second embodiment of an extender for sidewall of truck roof for use on the opposite side of a truck is a mirror symmetrical image that is not presently illustrated;
FIG. 2 is a rear elevational view of the extender for sidewall of truck roof of FIG. 1;
FIG. 3 is a front elevational view of the extender for sidewall of truck roof of FIG. 1;
FIG. 4 is a top plan view of the extender for sidewall of truck roof of FIG. 1;
FIG. 5 is a bottom plan view of the extender for sidewall of truck roof of FIG. 1;
FIG. 6 is a left side elevational view of the extender for sidewall of truck roof of FIG. 1; and,
FIG. 7 is a right side elevational view of the extender for sidewall of truck roof of FIG. 1.
The broken line showing of a portion of a truck roof is for the purpose of illustrating environmental structure and forms no part of the claimed design.
The extender for sidewall of truck roof shown in FIGS. 1-7 illustrates a first embodiment of our novel design suitable for use on the right sidewall of a truck roof. Our novel design also includes a second embodiment suitable for use on the left sidewall of the truck roof, which is mirror symmetrical to FIGS. 1-7 and, therefore, is not separately illustrated.
