Review on 10 Pack Blue XiKe 2-Inch Nylon Garage Door Roller with 4-Inch Stem - Quiet, Durable, High Load - Featuring 6200-2RS Double Seals Precision Bearings by John Holliday

One of the best DIY projects I've ever done. They run clean, smooth and quiet as advertised. They look like they'll last a lifetime right out of the box. I have a wooden garage door that weighs two meters and is two meters wide. As a precaution, clear the tracks first. Install the top four casters with the door facing down. The latter, together with the door, held it firmly in the UP position; Install the lower rollers as the bracket that holds these rollers is attached to the cable. {The cable is under minimal tension when the door is raised. I found that one of the cables was starting to wear out, so I replaced the cable, which can only be done with the bracket removed.}
