The "Ancient" is a replacement lock for a latch case that uses a highly secure NF cylinder (with 4 dimple keys) aimed at achieving higher security. The newly developed CTS lock features a fail-safe design. It alerts you when excessive load is applied to the lock or when the lock fails due to aging deterioration. Additionally, we also offer a two-lock case replacement lock for this product, so please feel free to contact us. 【Features of the CTS Lock】 ■ Even if internal components of the lock are damaged, the safety device activates, allowing normal locking and unlocking operations. ■ Damage to the internal components of the lock can be checked without removing it from the door. ■ If a red line is visible on the flat surface of the latch bolt, it is a sign that it needs to be replaced. *For more details, please refer to the PDF document or feel free to contact us.
