Cable Considerations
To install the cable in conduit, a threaded cable cap assembly
should be used (S653). Before the main rigid conduit a length
of flexible conduit (at least 6"longer than the insertion rod
should be used so that the insertion rod can completely clear
the adapter body (large body with 1" NPT that threads into ball
valve) for removal or the electrode.

S676 30" (76cm)
S677 36" (91cm)
