"PHE Simplex System of Steel

Conduits for the efficient encase-
ment of Electric Wiring Cable, con-
sists of a combination of smooth
bore Steel Tubes or Conduits, used
m conjunction with malleable cast-
iron fittings and accessories, so as to
form a complete Covering, specially
designed to meet the requirements
of high-class installation work, and
the saving of time and labour in
erection, with the further object of
effecting a general reduction in cost
of efficient Conduit Wiring.

The Simplex Conduit System
has been developed during a period
of many years, and is the outcome
of patient labour on the part of
our designing and manufacturing
engineers, whose energies have been
directed continually towards the bet-
terment of the Simplex Conduit
Wiring System. Many thousands of
installations, carried out on the
Simplex System, are giving con-
tinuous satisfaction in all parts of
the world to-day.
