Install Strain-relief Hardware
If at least 10 m (33 ft) of outside plant cable is routed within an environmentally controlled
building where temperature fluctuation is minimal, securing the cable sheath is adequate strain-
relief.
Step 1:
Place hose clamp over the cable and strain-relief bar 18 mm (0.75 inch) below the
sheath end. Center the sheath retention grip on the opposite side of the cable from
the hose clamp tensioning body (Figure 21).
IMPORTANT: When using armored cable, install strain-relief bracket(s) to the opposite side (180
degrees) from the location of the grounding clamp. Install the hose clamp and bracket
25 mm (1 inch) from the end of the cable sheath to prevent the retention grip from
overlapping the ground hardware.
Step 2:
If there is a central member
present, install the central
member restraint clip as shown in
Figure 22:

Step 3:
Tighten the hose clamp to secure the cable(s) to the strain-relief bar.
Step 4:
Tighten watertight fitting.
IMPORTANT: The watertight fitting must be tightened to prevent water intrusion into the enclosure.
