Frequently Asked Questions
Q1: Is this handle suitable for both left- and right-handed doors?
Yes, the handle is symmetrical and works on both left-hand and right-hand swing doors. It can also be used on sliding doors with appropriate glass cutouts.
Q2: What finish offers the best durability in high-humidity areas?
We recommend the brushed nickel or matte black finish, as they have enhanced resistance to fingerprints and moisture. For coastal environments, our optional 316 stainless steel screws provide extra protection.
Q3: Can I install this handle on a door with a glass thickness of 15 mm?
Our standard model fits 8–12 mm glass. If your glass is 15 mm, we can supply customized adapters or longer screws – please specify this requirement when placing the order.
Q4: How are the handles packaged to avoid damage during shipping?
Each pair of handles is packed in a foam-lined box with separate compartments for knobs, base plates, and screws. Outer cartons are reinforced with corner protectors. We have an extremely low damage rate of less than 0.5%.
Q5: Do you provide a warranty for this product?
Yes, we offer a 2-year warranty against manufacturing defects. This covers peeling, cracking, or loosening under normal use. After-sales support is available via email or live chat.
Q6: Can I get a sample before placing a bulk order?
Absolutely. We provide sample orders with a lead time of 3–5 working days. The sample cost is deducted from the first bulk order (minimum 200 pairs).
Q7: What is the minimum order quantity (MOQ) for custom engraving?
For custom logos or engraving, the MOQ is 500 pairs. Plain handles without customization have a lower MOQ of 100 pairs.
Q8: How long does it take to ship to the United States?
Shipments from Shanghai/Ningbo to major US ports (Los Angeles, Long Beach) typically take 20–25 days by sea. Air freight is available upon request (5–7 days).
