Par 7-182 Page 7-336 alloy. For safety cable diam eter of safety wire size and material, refer to table 7-8.
Care should be exercised when safety wiring, particularly where corrosion will present a problem, because smaller wire sizes tend to crack when twisted.

1 Galvanized or tinned steel, or soft iron wires are also acceptable.
SPECIAL LOCKING DEVICES. Several turnbuckle locking devices are available for securing turnbuckle barrels such as wirelocking clips. Persons intending to use a special device must ensure the turnbuckle assembly has been designed to accommodate such devices. A typical unit is shown in figure 7-26. When special locking devices are not readily available, the use of safety wire is acceptable.
ASSEMBLING AND SECURING CLIP-LOCKING TURNBUCKLES. (See table 7-9 and figure 7-27.) Wire clip-locking turnbuckles are assembled and secured in the following ways.
Engage threads of turnbuckle barrel with threads of cable terminal and turn barrel until proper cable tension is reached.
Align slot in barrel with slot in cable terminal.
Hold lock clip between thumb and forefinger at loop end and insert straight end of clip into opening formed by aligned slots.
Bring hook end of lock clip over hole in center of turnbuckle barrel and seat hook loop into hole.
Apply pressure to hook shoulder to engage hook lip in turnbuckle barrel and to complete safety locking of one end of turnbuckle.
NOTE: Repeat the above steps to safety lock the opposite end of turnbuckle. Both lock clips may be inserted in the same turnbuckle barrel hole or they may be inserted in opposite holes. Howe ver, do not reverse wire locking clips
