8.5' XL Heavy-Duty Flexible Signpost – Concrete Installation
The 8.5' XL Heavy-Duty Flexible Signpost 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 2-3/8" OD galvanized steel post with a rugged galvanized steel base and a concealed 5/16" thick steel spring. This flexible base allows the signpost to move through a 360° range of motion rather than remaining completely rigid, helping reduce damage associated with incidental vehicle contact.
Designed specifically for concrete installation, the system includes zinc-coated concrete anchors and a set of two double-sided sign brackets. The finished assembly stands 102" (8'6") high and is designed to support compatible steel regulatory or informational signs. Sign is not included.

Flexible 360° Signpost System
The XL flexible signpost differs from a conventional rigid signpost by incorporating a 5/16" thick steel spring into the base assembly. This allows the post to flex through a full 360° range of motion when contacted.
The flexible design can help reduce damage to the signpost, mounting area, and contacting vehicle during incidental impacts while allowing the post to continue serving as an elevated sign support.
Full-Height Sign Support
The 99" galvanized steel post provides a substantial mounting surface for compatible steel regulatory and informational signs. With the flexible base installed, the complete system reaches a finished height of 102" (8'6").
A set of two double-sided sign brackets is included with the system. The sign itself is sold separately.
Concrete Installation
This model is configured specifically for concrete installation and includes zinc-coated anchoring hardware for securing the base to a suitable concrete surface.
The base should be properly anchored before the signpost and sign are installed. The concrete substrate should be evaluated to confirm that it is suitable for the supplied anchoring system and intended 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

Also Available for Asphalt Installation
For projects with an asphalt mounting surface, this flexible signpost system is also available in an Asphalt 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 8.5' XL Heavy-Duty Flexible Signpost is proudly manufactured in the United States for parking, traffic-control, commercial, municipal, and institutional applications.
