- Height and Gap Compatibility: Measure door bottom clearances to choose an adjustable or fixed-height threshold that seals gaps from 1/8″ to 1 1/2″ high.
- Fire-Rating and Safety: If fire doors are involved, select thresholds with UL or local fire-rated compatibility to limit smoke and flame spread.
- Installation Ease: Pre-drilled holes, hidden screws, and included nails simplify setup and reduce visible hardware for a cleaner look.
- Maintenance: Metal thresholds resist weather but may need occasional cleaning; wooden inserts may require refinishing in humid climates.
- Width and Length: 6 ft thresholds come in various widths; confirm door width, threshold length, and whether you need an exterior, interior, or universal model.
- Climate Considerations: For extreme weather, aluminum with weatherproof seals provides consistent performance; wooden components may expand or contract with humidity.
