Questions about the installation method are resolved in one go with a video!
We have released a video explaining the installation of the "Keylex for frame doors" that can be installed on frame doors (doors with glass or panels fitted in the central part). The installation method for the throne replacement lock varies in four patterns: right hinge and left hinge, outward opening and inward opening. We explain the orientation of the latch and parts, as well as how to swap out parts for each pattern. This model is the only one that has a backset setting of 100mm! Additionally, we are also introducing installation videos for the "500 series surface-mounted deadbolt," which we receive inquiries about regarding hinge settings. We will continue to post examples that are difficult to explain without videos! ▽You can watch it from the link below!!▽
