The strain relief can be tightened in two ways, choose whichever is best for your
application:
a) Tightening onto plenum cable or bare wire -- Slide the wiring through the
strain relief fitting on the terminal cover plate. In the case of bare wire and
plenum cable it is often possible to provide acceptable strain relief force by
simply tightening the screws holding the sliding strain relief onto the terminal
cover plate. To achieve a tight fit, use a clamping mechanism (such as slipjoint
pliers) to hold the strain relief pieces together while tightening the hold-down
screws.
It is optional to reinsert the horizontal screw that was previously removed and to
tighten the two horizontal screws, clamping the wire securely between them.
