Review on Heavy Duty 12Ft Double Sliding Barn Door Hardware Kit - Smooth & Quiet Operation For 36" Wide Doors - J Shape Hanger Black | SMARTSTANDARD. by Bobby Diaz

I bought the 10 foot version for double doors opening in the middle. Very straight forward installation, I didnt read the instructions (did look at the pictures) and it came out perfectly. Heavy duty steel hardware except the wheels which are POM Polyoxymethylene (POM), also known as acetal,[2] polyacetal, and polyformaldehyde, an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. translation: a high quality smoothly rolling plastic wheel (doesn’t look or feel cheap). I’m so confident in this hardware that I am using it outside covering a French door under a covered porch. Hardware was actually higher quality and heavier duty than I needed, as my doors aren’t that heavy. (Could handle fairly heavy doors in my opinion). My only negative comment is the door guides at the bottom require you to router a grove in the bottom of your door for them to work properly. This method allows the guides to be unseen, but I didn’t want to hassle with the groove, so I just bought cheap barn door rollers (floor guides) from amazon and bolted them to the porch (visible, but easy install and door rolls smoothly.)
