Shop commercial-grade thresholds for hollow metal (steel) doors used in schools, offices, stairwells, hospitals, and exterior service entrances. These thresholds are designed for ADA accessibility, fire-rated openings, and real commercial traffic - not lightweight residential imports.
Tip: If you are unsure which threshold you need, start with our threshold hub and selection guides before ordering.

Choose the threshold type that matches your opening conditions:
Many low-cost thresholds sold online are not certified to the standards required for commercial openings. For hollow metal doors - especially fire-rated openings - using the correct, documented threshold helps avoid inspection issues and rework.
Door Closers USA stocks commercial thresholds intended for real code-compliant openings.
