Installation Steps For Spherical Door Lock

The installation of locks is also crucial: during installation, it is necessary to strictly follow the product manual, recognize the installation center distance, applicable scope, and lock opening method. Special attention should be paid not to install on wooden frame doors with high humidity to prevent corrosion from harmful substances.
A. Determine the center of the lock body and lock tongue based on the "fixed distance template".
B. Draw a circle from the two center points, drill a 54mm diameter lock body hole with a light drill, drill a 25mm diameter lock body hole with a back drill, and at the same time, drill a lock tongue socket.
C. Use the tip of the accessory to remove the inner handle.
D. First, install the lock tongue into the lock tongue hole on the side of the door, tighten it with screws, and then install the lock body. Insert it into the lock body hole from the inside, and at the same time, fasten the tail end of the lock tongue to combine the lock body with the lock tongue.
E. Adjust the position of the outer adjustment ring so that the center of the lock body is at the centerline of the door thickness.
F. Place the inner glove on the handle tube, press down on the positioning card with the closed end of the accessory, and then push in the inner handle to make them lock in.
G. If the lock can be opened flexibly with the key and the outer and inner handles, then the lock installation is correct.
