All Other Mounts
Standard: Twist tab (designated by “1”)
Special: Bend tab — 2 or 3 ears
Bracket mounted
Suggested Panel for Twist Tab
.042" thick (1.07mm)
Locating Lugs (Bushing Mount)
Standard: .312" (7.9mm) radius from center of control.
Special: .375" (9.53mm) radius from center of control.
Standard Position: Left side supplied unless otherwise
specified.
Other Positions:
Available with lug right side,
without lugs, or with lugs both
left and right sides.
Water Seal Construction
Controls are also available to prevent water
from entering the control through either the
O.D. of shaft and/or the bushing.
Concentric Tandem Units
Available in two combinations:
A
– .125" (3.2mm) diameter rear shaft
.250" (6.35mm) panel shaft
(3/8 – 32 or M9X.75)
B
– .156" (4.0mm) diameter rear shaft
.236" (6.0mm) diameter panel shaft
(3/8 – 32 or M8X.75)
Most metal shaft diameters can be used with
twist tab mountings. With bracket mount,
only .187 diameter shafts are used, with turn-down
available to obtain smaller diameters.
Metal
Lengths: Minimum .125" (3.2mm) beyond bushing;
special lengths as required.
Trims:
