FAQs

What type of doors is this knob suitable for?

This knob is designed for interior doors such as those for bathrooms, bedrooms, closets, and general living areas. It is not intended for exterior security purposes.

How do I know if this knob will fit my door?

The knob fits most standard doors with thicknesses from 1-3/8 to 2-1/6 inches (35-55 mm) and features an adjustable backset for 2-3/8 or 2-3/4 inch (60-70 mm) configurations.

Is the polished brass finish prone to tarnishing?

The polished brass finish offers durability, but like all brass finishes, it may require occasional cleaning with a non-abrasive cleaner to maintain its shine. Avoid harsh chemicals.

What is the durability rating of this door knob?

It meets ANSI Grade 3 standards, meaning it is tested to exceed 250,000 opening cycles, ensuring long-term reliability for everyday use.

Can this knob be used on a closet door?

Yes, it is well-suited for closet doors due to its durability and ease of use.

How do I clean the porcelain part of the knob?

Gently wipe the porcelain with a soft, damp cloth. Avoid using abrasive cleaners or harsh chemicals that could damage the glazed finish.

What material is the internal mechanism made of?

The interior mechanism, including the rose and latch, is constructed from a sturdy zinc alloy for long-lasting performance.

Troubleshooting

Knob is loose or wobbly.

Check that the mounting screws are tightened securely. Ensure the knob assembly is properly seated on the door.

Latch does not retract or extend smoothly.

Verify that the backset is correctly set for your door. Ensure there are no obstructions in the latch hole or the strike plate on the door frame. The latch mechanism may require lubrication with a light household oil if it feels stiff.

Door does not latch securely.

Check alignment of the latch with the strike plate. Ensure the strike plate is properly positioned and secured on the door frame. Adjust the strike plate if necessary.

Knob feels stiff when turning.

Ensure the door thickness and backset are within the specified ranges. A small amount of light household lubricant may be applied to the internal mechanism if recommended by the manufacturer, but avoid over-application.
