Not all door hardware is built for the same level of use.
That’s where hardware grades matter.
Grade 1 hardware is designed for heavy-use openings like schools and hospitals.
Grade 2 is commonly used in commercial spaces like offices.
Grade 3 is typically intended for residential applications.
The difference comes down to durability, cycle testing, and how much daily traffic the hardware is built to handle.
Understanding hardware grades helps you make better decisions before a project ever reaches the field.
