It sounds like your cabinet is not exactly square.
I am guessing that either or both that your drawer is not square or that the opening is not square.
I don't know about absolutely perfect, but the box, cabinet and drawer opening are all square.
The drawer goes in part way and stops because itís out of square and tightens up mid point.
It doesn't tighten, like gradually, it stops dead, as in hitting a brick (rather, plastic

My guess would also be you are hitting a screw.
I bought #8 3/4" screws to replace the 1/2" screws that came with the slides. They looked the same, but the cone behind the head does appear to be a bit proud. I removed the 3/4" screws and used the ones that came with them, but the drawer still won't go in.
The problem I'm having now seems to be a personal physical limitation. I can't hold the sides of the drawer and lean to see either slide to guide the drawer part of the slides into the cabinet side of the slides. It's a real struggle rassling with it and I got this breathing problem. The thought occurs to me that as my lung disease progresses, I may not be able to do any maintenance or major cleaning involving the removal and replacement of those drawers, even if I managed to get them working now. I've read a few stories about how these big box store slides tend to break or malfunction in too short a period of time.
You have a couple of options.
[1.]Probably easier to adjust the drawer than to adjust the cabinet if you stay with the slides youíve purchased.
[2.]Another option will be to toss the metal drawer slides and install wood drawer guides.
Yeah, I think either a different kind of slide. or wood guides. I'll do some more research and see what I can find. The wood drawer guides you described may not be able to accommodate a stop (well, maybe a pair of them on the sides) because the vanity carcass is mostly one big open hole for 3 inset drawers (see the pic for a reminder).
Thanks for the help and suggestions.
