Before You Begin

This is an overview of how this unit is installed in a closet doorway. Specific installation instructions are included with the unit. Read the instructions carefully and identify all the components. It consists of a valance, which is installed on the wall above the door, a threshold floor plate for the roller mechanism fastened on the floor and two bookcases joined by a piano hinge.

  • Step 1 : Remove the closet door

    Use a hammer to tap up the door hinges and remove the hinge pin. Then carefully pull the door out of its hinges and remove it.

  • Step 2 : Assemble the bookcases

    Remove the components and assemble the bookcases by putting the frames together with the locking cams and studs. Glue the back on the frame and a carpenter's square to square up the unit. Use brad nails on the back.

  • Step 3 : Hinge the bookcases together

    Use an electric drill to install the piano hinge that joins the two bookcases.

  • Step 4 : Attach the threshold

    Lay out the threshold and use masking tape to assure that it is properly aligned. Drill through the masking tape into the predrilled holes in the threshold. Then attach the stainless steel plate for the roller mechanism.

  • Step 5 : Install the valance

    Use a studfinder to locate the wall studs above the door opening. Then assemble the valance and upper support bracket using the predrilled holes and fasten the valance into the wall studs. Install the pivot shims.

  • Step 6 : Position the bookcases on the pivot points

    Carefully lift the bookcases onto the roller mechanism on the threshold and at the valance and align them.

  • Step 7 : Install the shelves

    When the bookcases are moving smoothly on the roller mechanism, install the book shelves.
