PART A - SIZES AND TYPES OF GUYS
Seven-stand utilities grade (high strength steel) guy of suspension stand is used for
communication guys. The sizes and minimum strengths of these guys or suspension stands are listed in
Table 2-1. Refer to FM 11-486-5 for information to determine the size of stand for a pole that supports
a particular number of wires or size of cable at a head or side guy. Procedures for the use of the guy rule
are also covered in FM 11-486-5.

Types of guys.
a. Anchor guys. Anchor guys are further classified according to their use as side guys, head
guys, and storm guys. Anchor guys, sometimes called down guys, are run directly from a pole or strut
to an anchor in the ground.
(1) Side guys. Side guys are installed at corner poles to hold the lateral strain placed on
corner poles. This strain is caused by a change of direction in the line (Figure 2-1).
(2) Head guys. Head guys are installed at poles where a line, or a portion of a line, dead
ends. Head guys hold the load placed on the dead-end pole by a line or a portion of a line, ending at the
point (Figure 2-2).
(3) Storm guys. Storm guys are two side guys placed on the same pole opposite each other.
They may be used separately or together with two opposing head guys (Figure 2-3). Storm guys are
placed as indicated in the detailed plan to ensure stability of the line in long straight sections and at
points of heavy change in grade.
