Stoebich Model P vs Smoke Guard 2500

The main difference is that the Stoebich Model P is a custom-made, high-temperature-rated, self-closing smoke curtain for very large openings (up to 32.8' x 24.9' certified), while the Smoke Guard 2500 (M2500) is a pre-engineered, UL 10D-rated fire and smoke system for openings up to 40' x 20'.

The Stoebich Model P uses a "Gravigen" drive that closes without external energy, and can be customized for high-temperature loads.

The Smoke Guard 2500 has a specific fire endurance rating and standard features for smoke and draft control systems.
