Unlike other bollards, this unique design positions the lens on the top of the fixture.  The clear lens is sturdy injection-molded acrylic (HC) or polycarbonate (HCD and HCF).  It attaches to the housing with an overlapping die-cast aluminum retainer ring.  For quick relamping, only four flush-mounted, stainless-steel fasteners need to be removed from the base.  Two silicone lens seals prevent moisture from entering the lens.  Optional decorative Dome Top or Extended Flat Top styles also are available.
