Installation
FIG. 84: CORD GRIP INSTALLED
• Use a box end wrench to hold the cord grip
assembly nut so that it doesn’t move when
tightening the Hex Nut.
• Use a box end wrench to tighten the Hex
Nut until the Cord Grip assembly is snug
against the rear cover. Do not over tighten.
Step 2. If you are installing a Cord Grip Assembly into a
location which requires drilling a hole into the rear
cover do the following:
• Locate the indent that is closest to the con-
nector you want to connect to.
• A 1” inch diameter hole is required when
using Hardy Cord Grip Assemblies.
• Place the rear cover on a secure, flat sur-
face preferably a drill press table.
• Place a wooden block under the location
of the hole you want to drill. This will pre-
vent ragged edges from forming when
drilling or using a hole saw.
NOTE: When using a hole saw make sure you use a fine
tooth hole saw and not the coarse tooth hole saw.
CAUTION: D O NOT USE A HOLE PUNCH . A HOLE PUNCH
MAY CRACK THE REAR COVER AND DESTROY THE NEMA
4X SEAL .
• Center the drill bit in the preformed cen-
tering indent and drill or saw the hole
through the rear cover.
• Use emery cloth and lightly touch up the
inside and outside surfaces of the hole to
remove any burrs.
• Slide the Cord Grip Assembly into the
hole in the rear cover. (See Fig. 85)
