【Peace of Mind Guarantee】 In the unlikely event of any defects not mentioned in the description, we guarantee returns and refunds. Please refer to "About Returns and Refunds" in my profile for details. 【About the Product】 This is a set of Miwa U9DA.CY (cylinder) and DA.TH (thumbturn). This is a Union specification, and the shape of the thumbturn differs from Miwa's (Image ⑤). Compared to Miwa's general thumbturn, it has a sense of weight and luxury. ※ The original part number and product name for Union are MCS01001 / Knob Cylinder Lock (Image ⑥). This is a sale of only the cylinder and thumbturn. ※ We have confirmed that both the cylinder and thumbturn can be locked and unlocked without any problems when actually installed in a Miwa LA case. 【About the Condition】 Although it is an unused item because we have checked the operation, we have listed the condition as "Like New". 【Cylinder Type】 U9 Cylinder 【Cylinder/Thumbturn Type】 ・Cylinder: DA.CY ・Thumbturn: DA.TH (Union Specification) 【Finish】 ST / Hairline 【Compatible Door Thickness】 33～42mm 【Notes】 ※ This is a set of cylinder, 3 keys, and thumbturn. The original box and instruction manual are not included. 【About Compatibility Confirmation】 ① Determine the main type of the lock currently installed on the door from the markings on the front of the door. ② Check the cylinder type of the main type determined in ① in the Miwa Web Catalog compatibility chart. If LA(DA).CY is listed in the cylinder type, it can be installed. Here is a link to Miwa Lock's general catalog ↓ https://www.miwa-lock.co.jp/miwa_smartphone/tec/products/webcatalog.html The compatibility chart is on pages 847-853. ※ If you let us know the front markings and door thickness, we can confirm compatibility for you. Please feel free to ask.
