Span Attachment
Attach the Messenger to a Drop Clamp
1. Separate the messenger wire from the cable using the 90° (scissor) pull of the messenger and the cable, separat-
ing the length of messenger wire needed to make the wrap; about 15 to 18-inches.
Note: Never use the drop clamp, a knife, or other sharp tool to separate messenger & cable.
2. Fit the cable and messenger wire into the drop clamp as
shown, so that the clamp bail is between the two.
3. Pull the messenger wire around the center of the bear-
ing surface as shown, toward the rear or drop-side of the
clamp.
4. Serve the messenger wire through the messenger wire
slots and begin the wrap about the clamp body, as shown.
5. Continue the messenger wire wrap for two full turns.
6. Serve the messenger wire through the bottom mes-
senger wire slot, as shown, to the drop-side of the clamp
and cut the excess wire away, or ground it to the strand.
CommScope does not recommend the use of the 2-4-4
Method or other methods of tying off the messenger
around the cable. Studies have shown that the cable’s
impedance will change and worsen with loading.
