Ease of Use

The patented Auto-Latch system features a single attachment point to hold and display roll-up signs, allowing for fast, simple setup and takedown.

Compact & Portable Design

When folded, the SZ-412-S measures just 6” x 6.5” x 24”, taking minimal space in your vehicle while remaining lightweight (only 22.85 lbs).

** If you are using a Bone Safety manufactured sign, then all you will need is the Auto Latch system that comes with the stand. If you are using another manufacturers sign, then you will need to call for the Universal Bracket option. **
