A: Before ordering, please measure three key dimensions:

1. Door Thickness: Standard interior doors are usually 1-3/8" or 1-3/4" thick.
2. Backset: The distance from the edge of the door to the center of the bore hole (usually 2-3/8" or 2-3/4").
3. Bore Hole Diameter: Standard doors typically have a 2-1/8" hole.
   Please refer to our detailed Installation Guides for step-by-step measurement diagrams.

Most of our door knobs and levers feature a universal, fully reversible design that works on both left-handed and right-handed doors. If a specific product requires handedness selection, it will be clearly indicated in the product options.

Currently, items listed exclusively in Brushed Brass do not have an upcoming Satin Brass variant. However, visually and aesthetically, our Brushed Brass and Satin Brass finishes are very similar—both featuring a refined, soft-brushed texture that complements modern luxury interiors seamlessly.

If you love a design, we invite you to order a sample or try it in your space first. For future product launches or new finish releases, be sure to subscribe to our newsletter, follow our blog, or connect with us on social media for official updates!

Yes! All of our core door hardware, levers, knobs, and cabinet pulls are precision-crafted from heavy solid brass for exceptional weight, durability, and a premium tactile feel.

Clean softly using a mild dish soap and warm water with a clean, soft microfiber cloth, then dry completely. Avoid using abrasive sponges, harsh chemicals, or bleach-based cleaners, as these can damage the protective finish. Please visit our Product Care page for detailed care instructions.

Standard US domestic transit usually takes 3–5 business days. Once shipped, you will receive a confirmation email containing your tracking number.

We strive to process orders as quickly as possible. If you need to modify or cancel an order, please email our support team immediately. Once an order has entered warehouse processing or has been shipped, modifications or cancellations can no longer be made.

Products marked as Pre-Order or Backorder typically fall into one of three supply scenarios:

1. In Stock at Our Overseas Origin Warehouse: If you require a quantity not available in our primary US inventory, please contact us before ordering to confirm stock availability. If available, your order will be dispatched promptly on business days and typically arrives within 7–12 business days.
2. In Transit to / Processing at US Local Warehouse: These items are currently being processed or restocked at our local US warehouse and will be ready for immediate dispatch shortly. Once checked in, standard shipping takes 3–5 business days.
3. Made-to-Order / Factory Production: For items that are temporarily out of stock, we can initiate custom factory production based on your request. Production and delivery for made-to-order items usually take around 1 month or longer.

If you have an urgent timeline or need to confirm exact delivery dates for pre-order items, please reach out to our customer support team prior to placing your order!

We offer a 30-day return window from the date of delivery. To be eligible for a full refund, items must be in their original, unused condition without any visible signs of installation or mounting, as installed items cannot be resold. Please ensure that all original packaging, hardware, components, and accessories are completely included when returning the product.

If a product needs to be returned or exchanged due to customer error (such as selecting the wrong backset, door thickness, or function), the customer will be responsible for both the return shipping cost and the shipping fees for dispatching the replacement items. We strongly recommend reviewing our spec guides or contacting our support team before placing your order to ensure perfect compatibility.

If our storefront has sufficient stock for your required quantity, you can also request an exclusive bulk discount code from us directly. By default, orders of 100 units or more qualify for a 10% OFF discount code.
