6' Flexible Signpost System – Asphalt Installation
The 6' Flexible Signpost System is designed for parking, traffic-control, and regulatory-sign applications where a full-height steel signpost is needed with the ability to flex when contacted.
The system combines a 1-5/8" OD galvanized steel post with a rugged galvanized steel base and concealed 5/16" thick steel spring. This flexible base allows the signpost to move through a 360° range of motion rather than remain completely rigid, helping reduce damage associated with incidental vehicle contact.
Designed specifically for asphalt installation, the system includes zinc-coated asphalt anchors and a set of two double-sided sign brackets. The 72" steel post produces an installed finished height of approximately 78" (6'6"). Compatible steel regulatory or informational signs can be mounted to the post. Sign is not included.
Features & Benefits
- Flexible Signpost Design: Provides an elevated sign-support system that can yield when contacted rather than remain completely rigid.
- 360° Range of Motion: Concealed steel spring allows the post to flex in any direction.
- 72" Galvanized Steel Post: 1-5/8" OD steel post provides a substantial mounting surface for compatible signage.
- 78" Finished Height: Flexible base raises the installed assembly to approximately 6'6" overall.
- 5/16" Steel Spring: Heavy-duty spring is integrated into the base to provide flexible movement.
- 9.5" Steel Base: 7-gauge steel base plate provides the mounting foundation for the assembly.
- Asphalt Anchoring Hardware Included: Zinc-coated anchors are supplied for installation on a suitable asphalt surface.
- Double-Sided Sign Brackets Included: Includes a set of two brackets for mounting compatible steel signs.
- Helps Reduce Contact Damage: Flexible construction allows the post to yield during incidental contact instead of acting like a conventional rigid signpost.
- Base Unit Warranty: Manufacturer states a lifetime warranty for the base unit.
- Made in the USA: Proudly manufactured in the United States.

Flexible 360° Signpost System
Unlike a conventional rigid signpost, this system incorporates a 5/16" thick steel spring into the base assembly. The spring allows the post to flex through a full 360° range of motion when contacted.
This flexible construction can help reduce damage to the post, mounting area, and contacting vehicle during incidental impacts while allowing the assembly to continue functioning as an elevated sign support.
72" Steel Post with 78" Finished Height
The system uses a 72" long galvanized steel post. Once installed on the flexible base, the complete assembly reaches approximately 78" (6'6") overall height.
A set of two double-sided sign brackets is included for mounting compatible steel regulatory or informational signs. The sign itself is sold separately.
Asphalt Installation
This version is configured specifically for asphalt installation and includes zinc-coated anchoring hardware for securing the base to a suitable asphalt surface.
The base should be properly anchored before the signpost and sign are installed. Pavement condition and substrate suitability should be evaluated before installation to ensure the anchoring system is appropriate for the application.
Common Applications
- Accessible parking signage
- Reserved parking signs
- Parking lots and garages
- Traffic-control signage
- Directional signs
- Pedestrian and vehicle areas
- Drive-through lanes
- Commercial facilities
- Municipal properties
- Institutional facilities
Also Available for Concrete Installation
For projects with a concrete mounting surface, this flexible signpost system is also available in a Concrete Installation configuration.
Important Application Note
This product is designed as a flexible sign-support and traffic-guidance system. Its spring-mounted construction allows the post to yield when contacted rather than function as a rigid protective barrier.
No certified crash rating, vehicle-impact rating, or specific impact-speed classification has been provided with the supplied product information.
Made in the USA
The 6' Flexible Signpost System is proudly manufactured in the United States for parking, traffic-control, commercial, municipal, and institutional applications.
