Standard Position: Left side supplied unless otherwise
specified.
Other Positions: Available with lug right side,
without lugs, or with lugs both
Metal
left and right sides.
Lengths: Minimum .1±5" (3.±mm) beyond bushing;
special lengths as required.
Trims:
Plain round screwdriver slotted, flatted,
knurled. Other trims available
upon request.
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.
Molded
Flatted and knurled with screwdriver slot available
in many lengths and diameters.
