I purchased 12 of the 13 Ball Nylon Garage Door Rollers that were very well priced. They appear to be good quality. It is the sealed type bearings. Only time will tell if the nylon will stand up to use I put them through. At the price I purchased them I got two extra just in case. They are already much quieter than the metal rollers. The older ones had been on their for at least 15 years and if these last that long, the next owner can replace them.
Double check the Manual to confirm it fits your door before buying. Look at the " Preparation/Planning section Page 3 "
Silent operation, you can't hear the door operate for the any room in the house. " Very happy with this "
Only took a few hours for me to install it alone. Shown it to a few people, I should get commissions.
Easy to pair with accessories. Added 2 homelink cars, 4 2 button openers KLIK3U-BK, 2 remote light controllers 825LM, 1 Keypad 877Max, 2 Door buttons 883LM
A great feature. The Smart Control Panel 880LMW (included) it has a motion sensor is built in. It turns on the remote light 827LM (included) and my 825LMs are connected to 2 LED shop lights. Instant Light and after 5 minutes auto off.I don't care about Wifi and did not set this up.
