Luff Tape Comments;

It is best that you check your extrusion and provide
X and Y. Use drill bits to check as they are exactly
in spec.



Note that older profurl units often mis state the luff tape size, calling for the
primary rope diameter not the finished size of the luff tape. We work only with the
finished size.



Below are some general guidelines, but don't rely
on this, rather use it to check your measurements.
