Sign Blank Installation Hardware for 3" Diameter Posts

When your project calls for a clean, secure way to mount a sign blank to a round post, this hardware kit delivers a simple and reliable solution.

Designed specifically for 3" diameter posts, this through-bolt system provides a stable mounting point for sign blanks up to 1/8" thick. The curved stabilizer sits flush against the post, creating a flat mounting surface on the front for your sign while ensuring a tight, professional fit.

How it works:

  • Drill a 9/16" hole straight through the post
  • Position the curved stabilizer against the front of the post
  • Attach your sign blank to the front face
  • Insert the bolt through the post and tighten from the back

The result is a strong, low-profile installation that keeps your sign secure and properly aligned.

Features:

  • Fits 3" diameter round posts
  • Supports sign blanks up to 1/8" thick
  • Curved stabilizer creates a flat mounting surface
  • Through-bolt design for maximum holding strength
  • Includes washers and nuts
  • Durable powder-coated finish for outdoor use

Ideal for wayfinding signs, retail signage, parks, campuses, and streetscapes where clean mounting and long-term durability matter.
