Mounting Options

The pole may be specified with a single tenon mount for pole top mounting or side drilled pattern. For multiple fixtures, an adapter should be used. A removable pole cap is provided for poles specified with side drill luminaire mounting.

Finish Options

Carbon steel poles may be specified as hot-dip galvanized per ASTM A123 and/or finish painted with our standard Millerbond Wet Coat Finish. Multi-sided stainless steel poles may be specified as frost (rust resistant stainless steel shot blast) finished or finish painted with our standard Millerbond Wet Coat Finish.
