Before you start: Mount the brackets.
Step 1: The gliding shoe shelf consists of a U-shaped part (A) and a gliding part (B). Begin by separating the two parts from eachother.
Step 2: The U-shaped part has three metal tabs and a metal knob on each side (located at the top) that locks the U-shaped part into the bracket click-in.
Begin with the left bracket click in. Align the metal tabs on the U-shaped part with the cut-out notches of the bracket click-in. When aligned, hold the front of the bracket and press on the frame at the back rounded corner until you hear it lock into place.
Repeat on the right side.
To reposition the U-shaped part: it is not necessary to remove the frame from the brackets. Simply tilt up the front of both brackets and remove them from the hang standards. Place in the desired location.
Step 3: When the U-shaped part is mounted, insert the gliding part with the shoe rack. Align the rollers on each side of the frame with the openings in the U-shaped part. Slide the shoe shelf part of the frame into the U-shaped part.
NOTE: To remove the U-shaped part from the brackets: insert and twist a small/flat object (for example a bracket cover, no metal) between the bracket and the frame in front of the knob holding the frame in place.  At the same time, place one hand at the back of the frame. With your thumb on the hang standard, gently push the frame forward with your fingers. The frame should now pop out of the bracket. Repeat on the other side.
