1.75 Inch ID x 250

I had just bought a new double-wide garage door, and looked at the rollers that came with it - looks like junk to me. I searched and found these, so as the installation happened, these rollers are in from the very start. Why wait a year or two and then replace the originals? Looking forward to a long smooth life from these!

My shopping experience went very well. Parts were easy to locate and order. Shipping was smok'in fast. Install was super easy and the garage door is now working like new again. Will use Preferred Doors again when the need arises. Thanks guys.

I choose 5 as the best. So simple to install and work right away. Fast delivery and great customer service.

This is an excellent seller, the item was as described and very fast shipping. When my need for doors or garage door equipment strides, I will most definitely return here.

I purchase this part after reading that this is the replacement part for my Genie screw drive is not working and this is the likely culprit of the cause. The part was inexpensive and came quickly. Followed the YouTube video on how to disassemble my Genie and replace this part. It was exactly the part that I needed for replacement. Now my garage door is functioning again.
