NACC VR mounting clamps may
be used to mount any cylindrical
capacitor with a 1" to 3" diameter
that is to be mounted in a vertical
position. Material is 1010 CRS,
commercial grade #4 temper ASI-
scale. Parts are finished with .0001
(nominal) zinc chromate plating.
Use for mounting CG types, PSU,
HC/NP and MPD/MPF types.
Material thickness is .035"
HB brackets are used with
PL or PLA end caps. The
bracket is assembled to the
motor or any suitable sur-
face by two screws in line at
any convenient position
within the center-to-center
dimension (C) shown in the
chart.
Material: .042 spring steel
with black parkerized finish

These clips, though designed for
capacitors, have varied applica-
tions to retain many cylindrical com-
ponents. They are used extensively
in the electrical and electronic in-
dustries to hold spindles, condens-
ers, capacitors, tubes, rods and
conduit. Clips have phosphate and
oil finish.

PL and PLA end caps are usu-
ally used with HB type brack-
ets. The drawing shown at left
is type PL for use with the
wiring through the bracket to
the motor. For off motor mount-
ing, use type PLA. See page
214 for a photo showing a ca-
pacitor and end cap mounted
in a bracket.
