Very few of the sliders out there utilize attachments points under the frame. Those that do must be using rivnuts or something equivalent if the holes aren’t threaded.
The main stress from lifting would be borne by the side bolts and the tensile strength of the 1/4 steel I would think (though I’m not an engineer!). Westcott’s underside attachments will help oppose any rotational force on the slider.
