How to Choose the Best Door Knobs
Understanding Different Types of Door Knobs
Passage Knobs: These are used for interior doors where locking is not required, such as closets or hallways. They offer basic privacy but no security.
Privacy Knobs: Ideal for bathrooms and bedrooms, these knobs can be locked from the inside, typically with a small button or turn-button, and often have an emergency release on the outside.
Entry Knobs: Designed for exterior doors, these offer security and can be locked from both the inside and outside, usually with a key and a thumb turn.
Dummy Knobs: These are non-locking knobs used for decorative purposes on doors that don't require closing, like French doors or cabinets.
Key Features to Consider
Material: Common materials include brass, stainless steel, zinc, and bronze. Each offers different durability, corrosion resistance, and aesthetic qualities.
Finish: Finishes like polished brass, brushed nickel, oil-rubbed bronze, and matte black affect the knob's appearance and how it holds up to wear and tear.
Style: Knobs come in various styles, from traditional round knobs to more modern levers and decorative designs. Choose one that complements your home's architecture.
Security Grade: ANSI/BHMA grades (Grade 1 being the highest security) indicate the knob's durability and resistance to forced entry.
Backset: This is the distance from the edge of the door to the center of the knob hole. The standard backset is 2 3/8 inches, but 2 3/4 inches is also common.
Installation and Compatibility
Ensure the knob you choose is compatible with your door's thickness and pre-drilled holes. Most knobs are designed for standard door preparations, but it's always wise to check the specifications. Installation typically requires basic tools like a screwdriver.
Frequently Asked Questions
What is the difference between a passage knob and a privacy knob?
Passage knobs are for interior doors that don't need to be locked, like closets. Privacy knobs are also for interior doors but include a locking mechanism for rooms like bathrooms or bedrooms, usually with a simple interior lock.
How do I measure the backset for my door?
The backset is the distance from the edge of the door to the center of the doorknob hole. Measure this distance; the most common sizes are 2 3/8 inches and 2 3/4 inches.
What does an ANSI/BHMA Grade 1 rating mean for a door knob?
A Grade 1 rating signifies the highest level of security and durability. These knobs are tested to withstand heavy use and resistance to forced entry, making them ideal for exterior doors.
Can I replace an existing door knob with a different style?
Yes, as long as the new knob is compatible with your door's existing pre-drilled holes and backset measurement. Most knobs are designed to fit standard door preparations.
What is the best material for exterior door knobs?
For exterior knobs, durability and resistance to weather are key. Solid brass or stainless steel are excellent choices due to their strength and ability to resist corrosion.
How do I clean and maintain my door knobs?
Regular cleaning with a soft, damp cloth is usually sufficient. For tougher grime or specific finishes, consult the manufacturer's care instructions to avoid damaging the finish.
