D Cable lashing clamps used in aerial construction to secure terminal lashing or ground wires to stranded wires.
D cable lashing clamps are designed for easy and permanent termination of lashing wires to messenger strand. They are commonly used in aerial construction to secure lashing wire teminations at any interruption to cable span continuity or at the end of lashing wire coil.

D Cable Lashing Clamp installation:
The first step in properly securing the nut is to place the groove of the clamp over the strand two inches outside of the first lashed cable support or cable suspension clamp. D cable lashing clamps can be used will all sizes of lashing wire and various ground wires (NO. 6 or B) and galvanized stranded wires (6M, 6.6M, 10M and 16M).
Next, cut the lashing wire leaving a 1/4" tail after being threaded through the bug nut. Before cutting the lashing wire, secure the lashing wire to the strand with a lashing wire grip. Similarly, before permanently or temporarily securing the ends of the lashing wire, tap the strand sharply a few times while maintaining a pull on the wire to remove any slack which may have been introduced in the lashing wire.
Then, wrap the lashing wire twice around the strand following the natural twist of the strand.
Fourth, bend the lashing wire back around the stud halfway between the stud collar or shoulder and the second washer. Do not wrap the lashing wire 360° around the stud. This mistake can lead to pinching, breakage and premature failure.
Once the wires are in place, tighten the terminal nuts. The nut can be tightened or loosened with a C-type socket wrench or a B-type ratchet wrench.
Finally, tuck the loose end of the washing wire into the nook in the top of the clamp, out of the way. Tucking the ends away will additionally ensure that the end of the lashing wire does not score the cable sheath.
When over lashing follow steps three and four, but secure the second lashing wire between two flat washers. Furthermpre, when terminating the ground wire, place the wire between two washers for the best electrical connection. Type D cable lashing clamps can be used to join two lashing wires where the first terminal is behind the second washer and the second terminal is between the two grommets for the first and second wires. However, this should not be used in spans as it prevents the lashing of a second cable.
