Dummy door knobs are single-sided "fake knobs." They are typically mounted on a door's surface or in its interior. You can use some of them on double doors because they come in pairs. There are no functional components in these kinds of door knobs. They work well for the inside of French doors as well as a small pantry or shallow closet.
Passage door knobs are similar to dummy door knobs. They are used to opening doors and moving between rooms but do not lock. For inner corridors, closets, and other areas without privacy locks, passage door handles are suitable. Additionally known as unkeyed knobs.
Keyed entry door knobs for safety and security, feature a lock and key mechanism on both sides. They are utilized on exterior doors such as patio doors, entry garage doors, and front doors. Some doors have an internal lock button that you press to secure them. When you turn the interior knob, the button unlocks. To lock or unlock the door, you turn a twist mechanism on one side of other keyed entry door knobs.
Privacy door knobs possess a button or twist lock that only functions from one side. A generic key can be used to unlock some privacy door knobs with button locks since they feature a pinhole on the exterior of the knob. These sorts of door knobs are frequently used in bathrooms, bedrooms, and other spaces where privacy is required but keyed locks are not necessary.
Door levers are frequently found on French doors; however, they can be used anyplace that regular knobs are. These are ADA-compliant for users with disabilities as they come in various sizes and are simpler to use than standard door knobs.
Handle sets To be installed on the outside of a door, handle sets have a handle and a key lock. They also have a deadbolt and a lever or door knob on the other side of the door. They are widely used on front doors and look good doing it. You operate a thumb latch on the handle set to open or close the door after you unlock it.
