The Heavy-Duty Standard for Rigid Aluminum Signs
The Watchdog SS621A Heavy-Duty Double-Spring Sign Stand is engineered specifically for the demands of displaying rigid .080″ aluminum signs in high-traffic work zones. Featuring a telescoping mast that raises 48″ signs to a compliant 84″ height, this stand combines lightweight aluminum legs with a robust steel spring system to "spill" heavy wind loads and keep your signage upright and visible.
Key Features & Benefits
- Rigid Sign Specialist: Purpose-built to support 36″ and 48″ rigid (.080″ aluminum) signs, making it the ideal choice for long-term construction projects.
- Extended Visibility Mast: The telescoping mast allows for variable height adjustments, capable of mounting the bottom of a 48″ sign 7 feet (84″) above the ground for maximum driver visibility.
- Dual-Spring Stability: Heavy-duty automotive-grade steel springs are designed to absorb wind gusts and turbulence from passing trucks, preventing the stand from walking or tipping.
- Lightweight Aluminum Legs: Fixed-length legs are constructed from aluminum to reduce carrying weight without sacrificing the wide footprint needed for stability.
- All-Terrain Leveling: Legs lock into multiple positions, allowing independent adjustment to keep the stand level on uneven ground, slopes, or shoulders.
- Integrated Flag Holder: Includes a built-in bracket to mount three standard conspicuity flags, adding an extra layer of visibility to your setup.
- MASH & MUTCD Compliant: Fully tested and MASH-accepted (WZ-427) for 48″ .080 aluminum signs, ensuring your site meets federal safety regulations.
