Features & Advantages

| Fall Prevention | When doors open, the lower handrail grid automatically deploys to prevent fall accidents; eliminates hazards from unstable door closing. |
| Automatic Handrail | During inspection, the upright grid automatically forms handrails, firmly preventing side falls. |
