WHAT HAPPENED

Kohnan Shoji has announced a recall for its Door Chain (with Mounting Screws) due to a critical safety defect. The ring strength of the door chain is insufficient, meaning the product does not provide the intended security capability. This defect could allow unauthorized entry, posing a risk to user safety and property protection. The recall was officially posted on the Japan Consumer Affairs Agency recall information site on July 19, 2023, and is referenced by the Ministry of Economy, Trade and Industry (METI) and the National Institute of Technology and Evaluation (NITE).

This issue matters because door chains are a fundamental security measure for homes and businesses. A product that fails to meet basic security standards undermines consumer trust and can lead to real-world safety incidents. The recall highlights the importance of rigorous quality control in security hardware. Consumers who have installed this chain may have a false sense of security, believing their door is properly secured when it is not.

Users who have purchased this product should take immediate action:

• Stop using the door chain immediately and do not rely on it for security.
• Contact Kohnan Shoji for a full refund or product return as instructed on the recall notice.
• Check the product packaging or receipt for the management number (00000031019) to confirm it is the affected item.
• Consider replacing the chain with a certified security product from a trusted manufacturer.
