Application
Used where flexible metal raceway is installed
in outdoor or indoor locations where exposed
to continuous or intermittent moisture
To positively bond conduit to box or enclosure
Features
Ability to install quickly with low torque effort
Ground cone design offers the following
advantages:
(1) Compresses metallic convolutions; provides high
quality ground contact with low impedance and
high raceway holding power (A)
(2) Single helical thread on ground cone is easy to
install without cross thread; accepts variations
in raceway diameters and convolution pitch (B)
(3) Rolled over edge protects conductors (C)
Sealing Ring Design Features
(1) Grips and seals at leading and trailing edge —
will not abrade raceway jacket (D)
(2) Provided with grooves on inside diameter
for anti-sleeving (E)
(3) Shoulders on both ends for extra sealing (F)
(4) Symmetrical shape assures foolproof assembly
Can be disconnected and reused.
Watertight/oil tight installation at box or
enclosure termination is assured by:
(1) External taper thread hub on 5331 series
and use of sealing gasket 5262 series (G)
(2) Captivated sealing O-Ring on 5361 series (H)
(3) Taper tapped hole on 5271 series
