When outfitting a commercial space with new door hardware, it is important to invest in knobs or handles that best fit your needs. Commercial door knobs are specifically constructed to withstand heavier traffic flows and more rigorous use than the standard residential door knobs. These specialty door knobs are made with heavy duty materials that are less likely to wear out or break during heavy use, but often come with warranties that will cover the costs of early repair or replacement.

Choosing Door Hardware for a Commercial Space

When choosing heavy duty door knobs for your commercial space, it is important to select hardware that is built for your specific traffic flow and level of use. Commercial knobs are graded by the American National Standards Institute (ANSI) as either Grade 1 or Grade 2 knobs. Grade 1 knobs are heavy duty knobs made for the heaviest traffic and use. These knobs perform well in commercial spaces like schools, hospitals, factories, public buildings, and industrial buildings. Grade 2 door knobs are made for moderately heavy traffic and use and are more fitting when installed in lower-traffic spaces like hotels, religious buildings, apartment complexes, and professional office buildings. Choosing the right grade of door knob or door handle for your commercial space will extend the lifespan of your hardware and save you money on knob replacements in the future.
