I got this 557/537 bottom box with top chest:
Most of the friction slides aren't working correctly. Or at least it takes a great deal of force to pull out all the drawers on the box, and most on the top chest.
When I pull out the drawers, many of the slides either slide all the way with the drawer, don't slide at all, or don't slide very easily (takes a lot of force to pull them and they don't glide out "smooth".
or the drawer slides out while the slides slide all the way off the rails:
or don't slide at all.
I'm going to take all the drawers out and remove the slides, soak them in solvent, and then grease them up.
Also the box was re-painted and I wonder if the the paint was put on too thick on the sheet metal "track" that's formed as part of the drawer itself. I'm going to try a wire wheel. Maybe this track is bent and it's not the friction slides themselves.
From my very limited experience w/SO boxes with friction slides, the top channel of a two channel friction slide is supposed to slide half-way out when the drawer is pulled all the way out? That's the way my KRA-59A works, and it appears to work flawlessly.
Anyway, almost every single slide isn't working on this box, and my understanding is that almost all of them are relatively new. So maybe it was the paint job.
