pins are secured with nichrome wire.
When securing the fiberglass guys, use
the guying grips supplied in the guying
kit, carefully following the instructions
provided. Use of alternative wire rope
grips is acceptable but ensure that:

The above recommendations should also
be used for any other guying, ie: stainless
steel, when used on any mast.
ERICO has standard 4 m (13 1 ⁄

ft.) and
7 m (24 1 ⁄

ft.) guying kits. If the guying
of a fiberglass mast is required, then the
appropriate guying kit should be selected
to suit the application. The guying material
is made up of light weight plastic coated
fiberglass, which is non-conductive.
If a customized guy kit has been supplied,
then the actual guy length can be
determined from the following:
Guy Length = 1.41 X
Where X = the vertical height between the
upper and lower guying points and the
assumed angle from horizontal is 45˚.
Important recommendations:

than 60° from horizontal.
