HEAVY DUTY 1/4" COMMERCIAL PHONE PLUGS
SERIES 188 AND 299 PLUGS
* Switchcraft's 188 is more heavy-duty than our
competitor's biggest 1/4" commercial phone plugs.
* Large curved tip solder terminal makes it easier to
solder to heavy gauge wires.
* Longer sleeve terminal allows more room to make
sleeve solder connections.
* Extra-large cable clamp securely grips cable of up
to .450" in diameter.
* Will easily accommodate some varieties of four
conductor 14 gauge wire and parallel two conductor
12 gauge wire.
* Bendable tab on sleeve terminal makes
termination easier by holding down cable while soldering. In addition, such
mechanical retention makes for a
superior solder connection.
* Will handle up to 15 A. rms (maximum).
