Straight “ST” and “STB” (Pages 3,4,5)
Series with grounding ferrule. “STB” series
has insulated throat. “ST” and “STB” sizes
3/8” to 5”.
45° “ST” and “STB” Series (Pages 3,5)
make some of the most difficult wiring jobs
easier. Sizes 3/8” to 4”.
90° “ST” and “STB” Series (Pages 3,4,5)
for use where there isn’t room to connect
straight off an encloser, which saves on
conduit and conductors. Sizes 3/8” to 4”.
Appleton’s “ST” and”STB” Connectors
(Pages 6,7) with an integral grounding lug
to provide visible positive external ground.
Straight connectors in sizes 3/8” to 5”, and
45° and 90° connectors in sizes 3/8” to 4”.
For use with liquidtight flexible metal
conduit where an external visible equipment
bonding jumper is desired and permitted by
the 1999 National Electrical Code Sections
250-96(b), 501-16(b) and 502-16(b) (where
external equipment bonding jumpers are
permitted, they will be limited to lengths not
exceeding 6 feet and will be routed parallel
to the conduit enclosure).
Bonded steel zinc electroplated lugs are
adequately sized to provide excellent
grounding continuity and allow for visible
ground path inspection. The ground wire is
easily installed using only an Allen head
wrench.
Liquidtight connectors with grounding lugs
can also be provided with Appleton’s
“STN”, “STL” and “Female ST” Connectors
(consult factory).
Space saving straight and 90° “STN” Series
(Page 10) with an insulated throat wedge
adapter designed to form a tight seal in
knockouts provides maximum wiring room.
Straight “STN” sizes from 3/8” to 4” and 90°
“STN” sizes from 3/8” to 1”.
90° “STL” Pulling Elbows (Page 11) have
one end for connecting liquidtight flexible
metal conduit. The other end has a close,
removable male nipple. Sizes 1/2”, 3/4”
and 1”. Straight Female Steel “ST”
Connectors (Page 11) with threaded hubs
in sizes 3/8” to 4”.
“STG” Series Liquidtight Neoprene Sealing
Gaskets (Page 11) for use where “ST”
fittings are terminated into J.I.C. boxes or
panelboards. Sizes 1/4” thru 5” fit all
Appleton “ST” series connectors.
The unique Appleton ferrule, long the
industry leader, provides maximum surface
contact for better sealing and grounding
and in preventing sleeving. This exclusive
ferrule design has now been modified even
further by an increased and improved
threading length that provides over four
times UL pull-out requirements.
Underwriters Laboratories list all Appleton
ST, STB and STN series connectors up to
the 4” size. The 5” size connector, though
manufactured to the same rigid standards,
cannot be listed as UL does not yet
recognize or list larger size conduit. They
are suitable for hazardous location use as
covered by the National Electrical Code:
Article 501-4(b): Class I, Div. 2; Article
502-4(a) 2: Class II, Div. 1 and 2; Article
503-3(a): Class III, Div. 1 and 2.
