Who it fits

Key specs explained for this knob

ANSI/BHMA grade 3 security

This rating indicates the lock meets basic residential security standards. It offers moderate durability and resistance to forced entry. You should expect reliable performance for interior bedroom or bathroom doors. This grade is standard for privacy knobs. It is less robust than commercial-grade locks. Compare this to higher security ratings if you need heavy-duty protection for exterior entry points.

Universal handing

The knob fits both left-handed and right-handed doors without modification. You do not need to choose a specific orientation during installation. This feature simplifies the process for standard interior doors. It reduces the chance of ordering the wrong side. This flexibility is useful for renovations. It saves time compared to non-universal models that require specific handedness selection.

Fits door thickness of 1-3/8" to 1-3/4"

This knob is designed for standard interior door thicknesses. You must measure your door before purchasing. If your door falls within this range, the hardware will align correctly. Doors outside this size will not work with this model. This specification ensures proper latch engagement. Always verify your door measurements to avoid installation issues or compatibility problems.

Material: Brass

The knob is constructed from brass, providing durability and a classic look. Brass resists corrosion and wear over time. You can expect a sturdy feel during daily use. The antique brass finish adds a traditional aesthetic. This material is suitable for high-traffic interior areas. Compare brass to plastic or zinc options for longer lifespan and better tactile feedback.

Design and build details

The listing states this knob is made from brass and finished in antique brass. According to the listing, the product is manufactured in China. The body measures 2.7 inches wide, 6.2 inches high, and 7.7 inches long. It weighs 15 ounces. This weight suggests a solid feel in your hand, which can help with grip on heavy interior doors. The finish is intended to resist tarnish and wear over time in high-traffic areas like bedrooms or bathrooms.

You will receive one knob, as the size is listed as 1 Count. The design is a bed and bath style, meaning it includes a privacy lock rather than a keyed entry. This layout is standard for rooms where you need to secure the door from the inside. The knob features universal handing, so it fits both left and right-handed doors without needing to buy separate parts. The adjustable latch allows it to fit standard door preparations, which simplifies installation if your door already has a hole for a similar lock.

The controls are simple: a turn button or push button on the interior side engages the lock. There is no keyhole on the outside. This design prioritizes ease of use over high security. You should expect it to hold up well for typical residential use. The compact size and standard dimensions make it a direct replacement for older knobs. You do not need to modify the door frame if the existing holes match the standard spacing.

Setup and everyday use

Installation is straightforward for most homeowners. The listing notes easy installation and handling as key features. This knob uses universal handing, meaning it fits both right-handed and left-handed doors without needing separate parts. You do not need to choose a specific orientation during setup.

The adjustable latch is a critical spec for fitting your door. It accommodates all standard door preparations. This flexibility simplifies the process if your existing holes do not match the knob exactly. The unit fits door thicknesses ranging from 1-3/8 inches to 1-3/4 inches. This range covers most standard interior residential doors.

For daily use, this is a privacy knob. It is designed for interior doors where a locking function is required. You should install it on bedroom or bathroom doors. It is not intended for front entry or high-security exterior applications. The ANSI/BHMA Grade 3 rating confirms its suitability for these lower-security interior spaces. This grade ensures moderate durability and resistance to forced entry, which is adequate for private rooms.

The brass construction contributes to its durability. The antique brass finish provides a specific aesthetic for your decor. The included hardware consists of the knob itself. You will need to ensure your door meets the thickness and preparation requirements before purchasing. Once installed, the mechanism offers reliable operation for everyday privacy needs. The universal design ensures it works seamlessly regardless of how your door swings.
