The sliding latch will move up to top notch and hold if your slide is in just do not forget to release it if you move your slide out.
Was working on a slide for a friend this weekend his back side of kitchen slide was off 1 1/2" and front side of slide was flush when slide was opened. He had a 1" space with stop nut before it would hit the stop braket at the rear end of slide.
Loosened allen set screws on sprocket wheel hubs and pushed the slide in rear of kitchen slide to bring up flush all around slide facia to wall. retighten sprocket wheel and slide is tracking in and out correctly.
He has alot of rust around slide supports and sprockets and we lubed them up for a better operation less noise when slide now operates.
The sprocket wheel will have a allen screw on its hub. Size of allen screw is 3/16" and you may need a socket wrench setup to loosen. If you have not lubed area your allen screws maybe rusted would use some penetrating oil to help free up screw.
This pic shows the key lock for shaft from motor do not remove this allen screw just want to loosen up sprocket wheel. on this locked shaft.
You have allen screws on shaft end that may not have to be loosened this ring on shaft should stay as it is. We want to turn sprocket wheel on this shaft.
Pic shows the stop rod with the double nuts to stop inward movement of slide. All four nuts should be tight and leave in place. This rod travels thru slot bracket that you see stop nut against.
This shows the nylon lock nut to stop the slide outward movement. On my friends slide this nut was not jammed against stop plate thus inside face plate of slide was out from wall about 1 1/2" from inside wall surface. Once we freed up sprocket wheel and pushed out slide so facia was flush against wall this stop nut was flush against stop braket as you see on mine with slide open.
Another view of stop nut against bracket on my opened slide.
