What’s the most common type of commercial door lockset?

It depends on the building. Offices often use cylindrical lever locks, hospitals may rely on mortise locks for added security, and exterior doors sometimes call for keypad or electronic locks. Panic bars are also extremely common since most commercial buildings are required to have fire exits.

What makes a door lock “commercial”?

Commercial door locks are tested to higher ANSI (American National Standards Institute) standards than residential locks. They’re usually Grade 1 or Grade 2 and built for heavy use in spaces like schools, museums, and offices. Grade 1 locks offer the highest level of security.

How high should a commercial door knob or lever be installed?

According to the International Building Code and ADA standards, knobs and levers should be mounted between 34 and 48 inches from the floor. There are some exceptions—for example, pool gates may require higher placement to keep kids from sneaking in.

We carry hundreds of options—from lever handles and knobs to panic bars, door closers, and more—from trusted brands like Falcon, Schlage, EZSet, and Deltana. Whether you’re outfitting a single office or an entire complex, you’ll find reliable products that combine durability, security, and function.

One key difference between residential and commercial door hardware is durability. Commercial hardware is designed to withstand constant use by hundreds (or even thousands) of people each day. When shopping, you’ll notice Grade 1 and Grade 2 ratings. Grade 1 offers the highest level of durability and protection, making it perfect for hospitals, schools, and banks. Grade 2 hardware is still strong and secure, but works best for offices or storage rooms where traffic is a little lighter.

We also know it can feel overwhelming with so many options. That’s why we make it easy to shop by function, brand, or style. You can even click “Shop by Function” to learn about the different lock functions before browsing products that match exactly what you need.

With many years of experience in construction and hardware, we get it. The smallest details can make the biggest difference. That’s why we’re here to help you choose the right commercial door hardware for your project. If you’re not sure where to start, give us a call and we’ll point you in the right direction.
