印度采购需求：转舌锁、执手锁、平面锁、连杆锁、铰链、搭扣

I'm interested in your hot-selling cabinet locks that operate without a key. Can you provide me with more information about the features and specifications? Specifically, I would like to know about the materials used, available sizes, and any certifications or safety standards the locks meet. Additionally, please share your pricing details, including any bulk order discounts, as well as the lead time for shipment. If you have a catalog or a product brochure, that would be really helpful for my evaluation. Looking forward to your prompt response!
