Main Level Door Knobs!

“Know What to Use When”

ADA compliance dictates that we need to use lever type knobs on the main floor level. You do, however, have design options. There are many different lever designs as well as finish options. This article will define the different types of functioning hardware. Your bathroom should have a different type of locking mechanism than your closet, for example.

Exterior or Outside Doors – The code has multiple options, however, in general, if your building or room has more than 50 occupants, you will be required to have a panic push bar like the one shown to the left.

Entry Lock – Generally speaking, for those buildings that do not have more than 50 occupants, this lock can be used. It has a push button locking system. The button on the inside locks the outside lever until unlocked by the key or by rotating the inside lever. The inside lever is always free. Be careful—it is easy to lock yourself out with this lock!

Office / Entry Lock – This lock can also be used on the exterior door of buildings that have fewer than 50 occupants. Think of this lock as a traditional locking system where the inside rotation of the level will automatically unlock the hardware. A key is used on the outside and a button for the inside locking mechanism.

Passage/Closet Latchset – This hardware latches at all times on both sides. There is no locking mechanism. Both levers will function and open the door. This door will remain unlocked all the time. This door is often used on offices, breakrooms, coat closets or other spaces that you don’t want locked at any time.

Privacy Lock – This hardware latches on both sides at all times. The outside lever provides a slot or small hole to unlock when the inside button is in the locked position. The lock will disengage when the inside lever is rotated. This lock is used in bathrooms most of the time.

Smith Residence - Front

Storeroom Lock – This lock is not used often. The outside level will not rotate. You turn the key, then pull or push the door open. The inside level will rotate and allow the door to open whether or not it is locked. You will keep people out but never in. This lock is used in storage rooms and janitor closets.
