A canopy line is a length of nylon cord that extends from a point of attachment on a connector link assembly
on one side of the canopy, up through a canopy radial seam channel, across the canopy vent, and down
through a canopy radial seam to a connector link assembly on the opposite side of the canopy. As a result of
the routing, a canopy line length is divided into segments that are referred to as suspension line, radial line,
and vent line. The procedures that follow include the repair and replacement of individual segments of the
canopy line and the entire canopy.
a. Stitch and restitch with thread, nylon, size E, that is contrasting in color to the fabric being stitched or
original thread being restitched. If contrasting color thread is not available, thread of matching color
may be used, providing all other specifications are met.
b. Straight stitching and restitching should be locked by at least two inches at each end of the stitch row
c. Zig-zag restitching should extend at least two inches at each end of a stitch row when possible. Zig-
zag restitching should extend at least ¼ inch into undamaged stitching at each end, when possible.
d. Restitch directly over the original stitching and follow the original stitch pattern as closely as possible.
The radial line portion of a canopy line will not be spliced. Whenever a
canopy line is to be spliced, the splice will be located either above the
upper lateral band or below the lower lateral band.
2. Splicing. A suspension line or vent line may be spliced one time as follows:
