Notes to everyone. All line sets that have been relined with the "WORLD
RECORD" trim since 2003 have the correct trim. PD has been producing
linesets to these measurements for quite some time, just in a different
format for production purposes. Therefore there has been no change to
the linesets just a change to the trim chart to more accurately measure
the lines.
A few things to keep in mind:
There is a plus/minus tolerance of 1 inch for the A lines and the
Steering Lines.
There is a plus/minus tolerance of ½ inch for the A-B, A-C, and A-D
differentials.
This tolerance is for new production. Once a canopy has been in use the
variances will change some possibly to a value outside of the chart and
tolerance. The changes should not be far off for though and they should
be rather uniform.
It is important to use the measuring guide in order to properly measure
the trim.
If you have followed the guide exactly and have a noticeable
discrepancy – double check your work, or ask a knowledgeable rigger to
do so. If you still have questionable results contact Rusty at PD
