When you say "on the wall", or "to the wall", do you mean on a platform? Or on a shelf? Or do you mean attached directly to the wall, as per the link above?
"but have not secured the screen to the wall yet"
Sounds like you are attaching the display directly to the wall. If so, there is NO reason to use the base.
Is the product you are looking for similar to the image posted above?
Just trying to help by responding to your choice of words.
If you actually mean placing the display on a shelf or platform, and are looking for wire (per the attachment below, taken from your manual), I know for a fact that Home Depot has dozens of different types of cable and chains from which you can choose, having bought some before for different application. You don't need to support the entire weight of the display - only enough to stabilize the unit in case it gets bumped or nudged. I've actually had a display on the stand alone for several weeks (but I don't have kids or pets running around) with no issues while awaiting delivery of a mounting stand.
