AR500 Window Cover — “Blackout Event” Edition

Description:
The Sentinel Slab™ is a hardened AR500 steel window plate engineered for moments when the world outside stops making sense and you need your perimeter to hold — no questions, no hesitation, no second chances.

Cut from solid AR500 and built for rapid, one‑person deployment, the Sentinel Slab™ locks into place with a cold, mechanical finality. Once mounted, the room behind it becomes a sealed, controlled environment — a place where your family’s safety isn’t left to chance or chaos.

When not in use, it stores flat and silent, blending into the home like a dormant shield. But when the atmosphere shifts — when the streets go dark, when alarms echo in the distance, when uncertainty rolls in like a storm — the Sentinel Slab™ becomes the line between “out there” and in here.

This isn’t décor.
This isn’t theory.
This is a hard stop for whatever tries to breach your space.

Built for households that refuse to be caught unprepared, the Sentinel Slab™ is the final layer of control in a world that doesn’t always give warnings.
