Stanley National N174-284 Hanger Barn Door 300Lb Zn 9In, No Size, No Color

Trolley does not allow for as much vertical adjustment as the original, so door with original trolley needed to be lowered. This created a minor problem with bottom stay rollers that was easily solved. Door with new trolleys may now roll more smoothly than with original trolleys when new.

Used three pairs between two 10x16 metal shop doors. The bolts were too long so I used different bolts. Now the doors work perfectly. We used to use an ATV with a winch but now a 10 year old can open the doors. All of the ones removed had plastic/nylon bushings. These ones have roller bearings which greatly reduce the amount of effort needed to operate the doors.

Easy to install and adjust. Used a pair to hang a door that weighs over 400 lbs and it rolls VERY easily.
