Mast Bases
ERICO supplies a range of aluminum bases
to suit:
t
ERITECH ® brand of FRP masts (aluminum
base with an internal mast spigot).
t
Aluminum masts (welded directly onto
the required length of mast).
Both base types have downconductor
exit holes in the base, required if the
downconductor is to be routed inside of
the mast. They also have identical mounting
hole dimensions which are shown overleaf.
Before the installation of the mast, ensure
that:
t
The free standing mast is supplied with
an appropriate spigot, suitable for either
internal or external mounting of the FRP
mast.
t
The downconductor is to be routed
internally or externally.
t
Provision is made for external or internal
mounting of LEC IV and access.
t
The downconductor is able to exit
through the base of the free standing
mast.
The free standing mast requirements for
foundations and erection are generally
handled by the mast manufacturers.
