reduced noise

My garage door had metal rollers , the original installer came to put a new spring in my 20 yr door wanted rolls Royce pricing $600 to replace with nylon rollers . I"m pretty handy I bought these about 30$ and saved a bundle it"s a piece of cat if you have the right socket wrenches. Bottom roller is tricky and dangerous if you do not know how to avoid a major accident. So do you homework look at different videos on line. Be safe.

as advertised

Work and fit is good. Could be 2" shorter.

These were easy to install and run very smoothly. Be sure to look carefully at each roller mount so you don't take things apart that you don't need to, like I did. Luckily it wasn't too difficult to remedy.
