## Product Description
## The Compact, Single-Spring Solution for Work Zones

The **Bone Safety SafeZone (SZ-412-S) Single Spring Sign Stand** combines lightweight portability with the wind-deflecting power of a heavy-duty spring. Designed for fast deployment, this stand weighs just 23 lbs yet provides the stability needed for 36″ and 48″ roll-up signs in active traffic environments. With its bright orange legs and compact storage footprint, it is a favorite for crews who need high visibility and easy handling.

## Key Features & Benefits

- **Single Heavy-Duty Spring:** The integrated spring assembly allows the mast to flex during wind gusts and traffic drafts, keeping your sign upright and stable without tipping.
- **Fast & Ergonomic Deployment:** Features both oversized pull pins and a convenient kick-release lever, allowing you to deploy the legs quickly—even while wearing heavy work gloves.
- **Independent Leg Adjustment:** Three separate height adjustments allow you to level the stand perfectly on uneven terrain, curbs, or sloping shoulders.
- **High-Visibility Design:** Bright orange powder-coated legs increase visibility for drivers and pedestrians, adding an extra layer of safety in urban and roadside work zones.
- **Corrosion Resistant:** Built with zinc-plated and powder-coated steel components to withstand harsh weather and resist rust over years of use.
- **Compact Storage:** Despite its rugged spring assembly, the unit folds down neatly, taking up minimal space in crowded service trucks.

## Bracket Options & Sign Compatibility

Customize your stand to match your existing sign inventory:

- **"Auto Latch" Bracket:** Choose this for the fastest setup if you exclusively use roll-up signs with plastic bottom pockets.
- **Universal Bracket:** Select this versatile option if you need to mount a mix of roll-up signs, including those with sewn fabric pockets or plastic pockets.
