Before you start: Install the hang standards and the brackets. Step 1: Place the gliding frame over the brackets with the side tabs of the frame aligned over the slots in the brackets. Make sure the locking tabs are in the correct position. The tabs should point towards the wall. Press downwards so that the tabs fully engage in the bracket slots. Push backwards until you hear a click. Step 2: Insert two screws into the back of the composite trim. Do not fully tighten the screws yet. Position the trim in front of the holes on the front of the gliding frame. Push in and then slide to the left to lock it in place. Then fully tighten the screws. Step 3: Identify which of the gliding frame cover plates is left and which is right. The flat side is the outside, and the narrower part of the “triangular” cover plate should point backwards. Attach the cover plates so that they sit completely flush against the front tabs of the gliding frame.
