Replacement hanging roller for a folding door

A quick learner from New Jersey says:
I'm looking to hang bifold door on the attached track (photo of track and dimensions).

On the dimensions, the track I provided the inside measurements. The outside dimensions are more like 1 1/2" wide by 1 1/4" height. thanks. The nylon wheels of the existing hanger is 1 1/8" dia, and 1/4" wide; 7/8" center to center, 1 1/8" outside to outside, and 9/16" space between wheels.

I'm planning on putting up doors and shutters on a porch so gal. or not prone to rust would be useful.

Thanks. Brad

I think you should consider either our 23-255 or 23-176S. What do you think? If in doubt, you can purchase a complete set with track. Look at our 23-250, 23-251 and 23-252.
