Choosing Schlage Commercial Door Knobs

Choose the operating function first when comparing Schlage commercial door knobs. This collection includes passage, keyed entry, storeroom, classroom and dummy models, along with specialized communicating, corridor, vestibule, hotel/motel, institution and exit-only listings. The function describes how the lock is intended to operate; the knob design identifies its appearance. Two knobs with the same shape and finish can have different operating functions, so match the complete model to the opening's requirements.

A-series and D-series model names provide a starting point for identifying the lock family. Orbit, Plymouth, Tulip and Georgian designs appear across the assortment, although the available functions vary by design and series. For an existing installation, record the full model number before comparing replacements. Keep any suffixes in that record, since a shortened model name may leave out information needed to distinguish the listed configuration from another similar-looking product.

Review the selected product's function description to understand operation from each side of the door. A room name alone is not enough to choose between entry, storeroom, classroom or other lock functions. For projects involving several openings, work from the door schedule and identify the required function for each location. Selected electronically locked and electronically unlocked D-series models also appear here; confirm their electrical and control requirements in the model-specific documentation before including them in a project.

Next, compare the lock's installation requirements with the opening. Check the backset, door thickness, bore preparation, latch and strike information, then confirm the cylinder configuration and keyway for keyed models. If the building has an established key system, verify the selected configuration against that system's requirements. Review what comes with the exact item and identify any separately required components, especially when replacing only part of an existing hardware arrangement.

Finish and design can be selected once function and fit are established. Compare the knob with nearby hardware, including any separate deadbolt, and review the finish offered for the chosen model. If your project specifies a lever, use the Schlage commercial door levers collection to compare those options. Keep the series, complete model number, design, finish and keying instructions together when preparing an order so that each door receives the intended configuration.
