Look for the brand stamped on the faceplate, and check for the Secured By Design logo. If the lock is still installed, a small black snib below the latch can help confirm its identity. However, be aware that other brands like ERA and Kenrick may also have similar features. Ingenious locks are characterized by a central hook that throws downward, distinguishing them from deadbolts.\u003c\/p\u003e\n\u003cp\u003eFor the most accurate identification, we recommend removing the multipoint lock from the door, especially if the brand is not visible or if it has been rebranded.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGearbox Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIngenious gearboxes are notable for their double spindle arrangement, with centers at 62mm and 92mm.
