Double Post Outboard

A double post assembly is designed to create a finished look for assemblies with wider panels. This assembly also accommodates mounting sign panels on both sides as signs are mounted to a common receiver panel (front and back).

Most common double post outboard assemblies are for panels 32” to 48” wide, but Terrabilt accommodates double post assemblies for 16” and 24” wide panels as well if this look is desired for narrower assemblies.


  • Double sided mounting uses common receiver panel: same size on both sides.
  • Fused image graphic panels (FIA) are printed on both sides for ease of upgrade if damaged.
  • Retroreflective panels (TRR) are imaged on one side only.
  • Accepts modular panels for 16”, 32” and 48” widths and 12”, 24, and 36” mounting heights
  • Standard posts are 3.5” x 3.5” (4” x 4” nominal), 4.5” x 4.5” (5” x 5” nominal) and 5.5” x 5.5” (6” x 6” nominal) depending on desired look or size of assembly.
  • Mounting height varies based on sightlines and program design.
