I have two doors on my pumphouse which doubles as sort of a shed for the yard tools being it's about 3x too big for the pump equipment in there.
The doors are made from 3/4 plywood (maybe even better) with a frame built on the back of them to stiffen them up. Each door is 4ft wide by 5ft 6in tall. They seem pretty nicely made, but when they were hung on the track, someone used the wrong hardware. I can't tell if the track is intended for a closet door, but the rollers definitely are closet door hardware, and they just won't hold up the heavy doors.
What kind of hardware should I be using to support these two doors properly and allow me to operate them easily without them falling off the track.
