- Door speed and weight specifications
- Controller compatibility for electronic components
- Local code requirements and fire ratings
OEM vs Aftermarket Parts
For door components, the choice between OEM and aftermarket depends on the part type:
- Safety components (interlocks, contacts): OEM recommended for code compliance
- Wear parts (gibs, rollers): Quality aftermarket often acceptable
- Door operators: Consider both; aftermarket can offer upgrades
- Sensors: Universal options available with proper integration
