1.75 Inch ID x 192

Part arrived as expected, great instructions included, opener works great now. It is much quieter than before.

My wireless garage door keypad was shipped quickly and arrived sooner than expected. I was able to quickly install and configure it so operate my door. The price was more than fair for a keypad from the door's manufacturer. I am very pleased with my purchase and would recommend Preferred Doors to friends and family.

Excellent company with quality products. They were fast and when I ordered the wrong part they were quick to send me a return authorization and a new part.

Excelent Services and communication with Joey.

Product was exactly as advertised. Sears wanted over twenty dollars for the same product. Preferred Doors price including shipping was $5.95. If I ever need other items for my garage door openers, I will certainly be a return customer. Extremely Satisfied Customer
