Tim, I am not sure what you are referring too. Maybe you mean the slide locks. FR provided four of them for the front slides that are hydraulic. They are cylindrical devices with a turnbuckle screw that you wedge between the wall and slide flange (when slide is in), to prevent the slide from popping out while driving (which has happened to several).
Problem is that the slides appear to have a flange going all the way up and around (wooden molding), but the slide locks will jus pop the decorative molding off.
Could be you mean something else.
