a. Types of clamps. Three types of strand clamps (Figure 2-23) are used to secure the ends of
guy strands. They are bolt, automatic-locking clevis, and the automatic-locking connecting types.
(1) The bolt-type strand clamp, which has two grooves for the guy strand, is made in one-
and three-bolt sizes. These clamps may be used to secure the end of a guy strand to the main part of the
guy, or to connect two ends of strand coming from opposite directions.
(2) The automatic-locking, clevis-type clamp consists of a U-shaped bail; a yoke; and a cone-
shaped, self-locking strand vise. The strand vise is designed to permit a strand to pass through the vise
in one direction only. The vise automatically locks to prevent the strand from being pulled back through
the vise. The clevis-type clamp may be used to attach one end of a strand to a thimble eyebolt, anchor
rod, or strain insulator.
