Resistor Mounting Hardware
For 200, 210, and 270 Series Resistors
MOUNTING BRACKETS
Brackets fit inside cores of 200, 210 and 270
type resistors and remain in place by spring ten-
sion. Standard brackets are plated steel and have
no suffix to part number. Spring steel brackets
are indicated with an “S” suffix following part
number.
WASHERS
THRU BOLTS
Thru-Bolts, with centering mica insulating wash-
ers, permit perpendicular mounting of 200, 210
and 270 type resistors to panels up to 0.25” thick.
ADJUSTABLE LUGS FOR 210 SERIES
One standard screwdriver type adjustable lug is
supplied with each unit.
Two types of lugs can be ordered separately:
standard or with a silver contact button; both
types are available with a screwdriver type lug.
Double thumb screw Lug
(Part Number 2160) The double thumb screw
adjustable lug permits easier adjustment and less
chance of damage to resistance wire. Available
for 1.125” cores only.

THRU-BOLTS AND MOUNTING BRACKETS
Sturdy plated steel brackets, along with thru-bolts, centering washers and insu-
lating washers (included), allow for secure mounting of 210 type and 270 type
resistors. Mounting brackets are available in either slotted (one with end-slot/one
with side-slot) or elongated styles.
