Next, install the link assembly pivot onto both bedsides through the lower holes again using the supplied 5/16-18 button head screws. Place the provided stainless flat washers on these pivots before attaching them to the bedside. This keeps the link assemblies from rubbing directly on the bedside. The link assembly pivots can be held with a 7/16-inch wrench while tightening the button head screws. Position the flats of this pivot horizontal as shown. Both of these items should be on the inside of the bedside with the button head screws on the outside.
