How to install the sliding door lock


Single-leaf sliding door

When installing a lock for a single-leaf sliding door, you only need to install the lock directly on the door cover and the door frame. If you want to lock the sliding door, you only need to move it to the position of the door cover.


Double-leaf sliding doors

The sliding doors of double-leaf doors basically overlap, so it is definitely more difficult to install the lock in the middle position. Therefore, it is necessary to install the lock on the sliding door on both sides. Normally, just open one.


Multiple sliding doors

Some sliding doors have four doors. At this time, you can use small nails to fix the sliding doors on both sides, and the horizontal rows in the middle are more convenient to install with the lock. They only open when in use. The two in the middle will do.
