in Vertical and Horizontal Position Without the Use of Wood Crossarms, More
than 750 Volts (Vertical and Triangular Construction)
G.
Allowable Climbing
Space Obstructions
Allowable climbing space obstructions
in triangular and vertical
configuration without the use of wood crossarms
are:
(1) Crossarms, brackets, and their supporting members.
(2) Insulators
which support line conductors, jumpers, and
incidental wires may
extend one–half of
their diameter into
the climbing space.
(3) Conductors
may extend one–half of
their diameter into
the climbing space.
(4) Suitably protected
(covered only by wood, see Rule 22.8):
(a) Vertical
risers; or
(b) Vertical runs; or
(c) Ground
wires.
Such risers,
runs, and grounds
are
allowable provided that
not more than one is installed
in any 4–foot section
of climbing space.
(5) Guys (except
those guys which
are metallically contacting metal pins or deadend
hardware as specified in Rule 52.7–
D). However, not more than two guys having
a vertical separation of 18 inches or less can
be installed
in any 4‑foot section
of climbing space.
(6) Street light
brackets
may
extend one–half their diameter into climbing
space. Associated street light bracket
struts are allowed
in climbing space.
(7) Operating
rods (e.g., switch rods)
and their associated
hardware may extend
one–half their diameter into climbing
space.
(8) Bands, limited to 6
inches in width with no more than
one band allowed in
any
24–inch section
of climbing space (these limitations are excluded for pole
stubbing and pole splicing bands when pole step provisions
are
installed.)
(9) Bolts and their washers. If
bolts are bonded,
a secure electrical
contact shall be
made. The
covering of bolts
and bond wire is not required in triangular
and vertical configuration
without the use of wood crossarms.

only
by wood (see Rule 22.8‑B);
2) Vertical
runs; or Ground wires covered
by
wood per Rule 22.8‑A1;
3) Ground wires covered by plastic, or other non‑conductive material no greater than
one‑half inch
in diameter (see Rule 22.8‑A3).
Such risers, runs,
and grounds are allowable provided that not more than one is installed in any 4–foot section of climbing space.

without the use of wood crossarms.
Reasonable efforts
shall be made to avoid
installing the above listed
allowable obstructions within
the climbing space.
