Illustrated Features
Flexibility and Ease of Use
Precision threaded wirebox and cover allows
hassle free access to power leads for easy wiring
and maintenance in challenging conditions.
Cover is secured with a safety chain to prevent
accidental disengagement and enhances
workplace safety
Choose from three color temperatures (CCT): 3000K, 4000K, and 5000K
Standard linear light distribution pattern: wide distribution maximizes spread and work plane brightness to optimize number of
luminaires needed
Configurable Options
Notched position locking mechanism
enables multiple fixtures to be aimed
consistently without spending significant
time
Rigmaster offers a NPT hub on each
end for through wiring. The power
leads are placed inside the wiring
compartment and can be easily
accessed by removing the tool-less wire
box cover
Mounting Brackets : Choose to mount your
Rigmaster using one of these distinctly designed
brackets to best suit your installation needs. All
brackets can be factory installed to save time in
the field or purchased separately.
Safety Features
ERMLSB Large Swivel Bracket:
Can be used to tilt and aim the fixture
up to 90 degrees in increments of 15
degrees using the pre-notched locking
mechanism
EXPLOSION PROOF LED LINEAR: NEC/CEC
Safety cables : can be purchased separately
or included with fixture to reduce ordering and
receiving complexity
Brackets and safety cables can be ordered separately or included with fixture. See Ordering Table for more information.
Up to four points for secondary retention
provide protection against infield
vibration.
ERMLPB Low Profile Bracket: This
fixed position bracket can be used to
lower overall mounting profile in low
ceiling applications
