How to Use
Step 1: Make sure that the installation position is firm and measure the
installation distance.
Step 2: Open the fixed lock, rotate the fixed heads at both ends, and extend
the horizontal bar until both ends are against the door frame or wall.
Step 3: Adjust the height of the fixed heads on both sides until the spirit
level is centered, and then rotate the middle rod to extend the two ends
until the middle rod cannot be rotated.
Note: Please make sure that the middle rod cannot be rotated in the
direction of the rotation arrow. This is the most critical in ensuring the bar is
firm.
