Unless otherwise specified, standard location is 3' above base and
90° from handhole (clockwise when facing single arm/drilling)
Vibration Damper (Option "V")
because of a phenomenon caused by local peculiarities of the site
and/or prevailing winds, poles may be susceptible to wind induced
harmonic vibrations in the 10 to 20 MPH wind range. Vibration
dampers which alleviate this condition are available.
Standard Convenience Outlet (Option "C")
Unless otherwise specified, standard location is 4' above base on
same side as handhole. (For GFI convenience outlet, specify option
handholes are furnished on all poles with standard bases. Poles with
alternate bases will have a handhole only where there is no access
in the base.
are furnished with a 5/16"-18NC-2 standard tapped hole inside the
pole or base for grounding purposes. If a ground lug is required
order as option G. Assembly is then provided with Dossert copper
ground lug or equivalent.
Optional Transformer Base
Vibration Pads (Option "F") Where poles
are installed on bridges, motion of the bridge structure itself can
transmit vibration into the light pole, with adverse effects on arms
and luminaires. To minimize this problem, vibration pads and washers
are available, along with installation instructions.
For most bridge applications, a combination of
vibration damper and pad is a wise investment. For further
information about vibration dampers and pads, contact your local P&K
