RS, RSM and RSS Junction Boxes
Conduit Hub Plates and Gaskets
6F-9
Application:
RS, RSM, RSS junction boxes
are installed in conduit systems
to:
• act as pull box for conductors
• provide openings and space
for making splices and taps in
conductors
• provide for branch conduit
runs
• provide access to conductors
for maintenance and future
system changes
Features:
• Junction box bodies accept
wide range of hub plates
permitting varied hub
arrangements and sizes.
• Stocking a few components
provides for many specific
needs.
• Future system expansion
easily accomplished by
substituting hub plates for
currently installed plates.
• Suitable for use where boxes
with integral hubs cannot satisfy
requirements.
• Suitable for surface mounting
outdoors or indoors in rigid
conduit runs.
Standard Materials:
• Bodies and hub plates Feraloy" iron alloy
• Gaskets - cork
Standard Finishes:
• Feraloy iron alloy electrogalvanized and aluminum
acrylic paint
