The Takigen cremon (gremon) handle is a multi-point lock used for a shelter, cubicle, soundproof door or electromagnetic protection door. It enables two or more locks to be lockable and unlockable by turning one handle. It is available in many variations such as the lock with an inner handle to allow door opening from the inside, with an attachable/detachable handle to prevent mischievous use, and a lock-attachable handle.
