Description
The SS420A heavy duty double spring sign stand is designed for rigid traffic signs in demanding work zone environments. Constructed from aluminum, it combines strength with reduced weight for easier handling.
The double spring design allows the sign to flex under wind load, improving stability and durability in harsh conditions. A telescoping mast raises the sign higher than standard stands, while fixed legs lock into multiple positions to adapt to uneven ground or sidewalks.
This stand includes rigid sign mounting brackets and built-in flag holders, making it a complete solution for high-visibility setups.
