I inherited from my grandmother six shelving units with sliding glass doors -- the glass doors aren't installed IN the units with rollers or anything, you just stick them in there and they run along these grooves in the wood.
The problem is, I have hardwood floors and every time I walk by them, the glass doors make this unnerving rattling noise that grates on my nerves. I've tried putting various things, coins, pieces of folded paper, etc, in the tracks and on the edge of the doors to perhaps "cushion" the doors so they'll JUST SHUT UP but nothing seems to work.
Does anyone have any suggestions as to how to MAKE THIS STOP?? (I mean, aside from perhaps not trundling about like a rhino when walking in front of it, but I'm a rather big dude so that's a little hard..... :sheesh
