Application
• To couple and effectively
bond threaded ends of rigid metal
conduit/intermediate metal conduit
where neither length of conduit
can be rotated
Features
• Malleable Iron/Steel/Copper-free
Aluminum construction
• Free fitting threads ensure easy assembly
• Permits conduit coupling
without rotating either conduit
• Provides rigid in-line coupling
with high- quality grounding;
will not loosen under vibration
• Suitable for concrete-tight application
• Capable of carrying ground fault
currents up to 10,000 amps RMS
(
1
⁄2" through 1
1
⁄2" size) and up to 20,000
amps RMS (2" and above) (duration of
fault current 3 cycles) (674 series tested)
With an ERICKSON
®
coupling, a conduit run
may be completed when neither conduit can
be turned. A conduit run may also be broken
without taking down the whole run. Conduit
joined with ERICKSON
®
Couplings is rigid and
in line and vibration will not loosen the
connections. Malleable iron.
