Slide Guide

I have a wooden sliding “barn” style door with a wooden channel that is guided by a floor mounted metal pin.  Over time, the pin has dug into the door quite a bit and carved a small maze into it that makes it hard to open and close.  The door can also just barely move past the pin and swing outside getting it stuck and damaging the outside of the door as well.

If you have something like this, then a simple Slide Guide is a life changer.  The door moves much more freely and reliably.
