TYPE YGLR-C
GRIDLOK
High Strength
Irreversible
Compression Ground Rod to
Grid Connector
Ground grid connector for a wide range of
copper cable to ground rod. Provides high
torque strength on ground rod. UL467
Listed. Acceptable for direct burial in earth
and concrete. Prefilled with PENETROX™
compound and strip sealed.
When attaching connector to ground rod, ground
rod must be embossed with appropriate PRE-
CRIMP™ die. For connections that must meet IEEE
837 requirements UPRECRIMP - type PRE crimp
dies must be used for maximum clamping reten-
tion.
NOTES:
1. Before crimping, both connector elements can
be turned on rod diameter 'D' to any desired
position.
2. Grooves are filled with PENETROX™
.
3. Suitable for direct burial in earth or concrete.
4. The catalog numbers shown are for unplated
copper connectors for use on copper clad or
stainless steel ground rod. To order electro-tin
plated connectors for use on galvanized steel
ground rod add suffix “TN” to the catalog num-
ber, only if the Figure 8 connector (Element “B”)
is tin plated, the Figure 6 connector (Element “A”)
is unplated. Note: The ground rod hole diameter
is larger for galvanized steel ground rod in the tin
plated connector.

Element A
5. Ground rod must be pre-crimped with die
U2CABT (Index No. 348) when crimping the
ground rod element (Element “B”) with the PU998
dies in the Y750, Y35, Y39, Y45, or Y46 tools.
Pre-crimping is not required when the S1012,
P1011 or U1011 dies are used. See precrimp die
chart.
6. Where a 'U' or 'PU' die is recommended with the
Y45 HYPRESS™, a PT6515 adapter must be
used.
7. Where a 'U' or 'PU' die is recommended with the
Y46 HYPRESS™, a PUADP-1 adapter must be
used.
8. Dimensions in bracket [ ] are in millimeters.
9. Die “1011” appears on Element “B” of the
connector only.
