Set the closed tabletop on the floor with the bottom face-up.
Measure 6 inches left and right of the center along the seam made by the two leaves of the tabletop. Mark these two spots with a pencil.
Draw two parallel lines on the marks at a 90-degree angle from the seam with a ruler and compass.
Clamp a closed equalizer slide to each parallel line. Center the middle section of the slide at the tabletop seam.
Mount the equalizer slides to the tabletop with the screws provided and a cordless drill. If the slides didn't come with screws, use screws that are 1/2-inch shorter than the thickness of the tabletop.
Attach the center beam, included with the equalizer slides, to the slides by aligning the pre-drilled holes at each end of the center beam to the pre-drilled holes on the middle section of the slides. Use the screws provided or 1-inch wood screws.
Mount the pedestal foot to the center of the center beam with 1-inch wood screws or the original screws for the pedestal foot.
Turn the table over and stand it upright. Open and close the leaves to check the movement of the equalizer slides.
