💡 Why do contractors prefer sealed ball bearing hinges over plain pin models for heavy interior doors?
Switching to ball bearing hardware keeps your setup handy since fewer moving parts mean way less downtime.
- Precision spun steel balls distribute weight evenly across the knuckle to stop door sag before it starts
- Grease packed chambers trap dirt away from the pivot zone while boosting durability for daily commercial use
- Flat plate design aligns cleanly with standard frame grooves so you can mount faster and skip extra prep work
