There are over 258 makes and models of rollers for sliding glass doors.
Assuming you find the right one, then you normally have to spend a good bit of time to take the entire bottom of the door off to get the rollers out. Oops, wrong roller. Put it all back together & start over. What a pain!
They are a "Wham-Bam" repair that should virtually last a lifetime!
These universal sliding glass patio door roller replacements are 4 inches long and each one is made out of really hard, slippery, strong, Teflon impregnated plastic. This durable material is designed to be used for highly abusive applications, such as chain guides for heavy equipment.
Basically, you put a hard slippery plastic on the roller rail and the "Slide Guide" is inserted in the frame in front of both of the existing patio door rollers with the groove facing down. The groove straddles and rides on the plastic covered roller rail making the door slide straight, easily and quietly. Thereby the "Slide Guides" take the place of the sliding door rollers. No need to remove existing sliding glass patio door rollers!
Doors slide like new! Quiet too!
They come with shims to make sure they fit most every door.
Designed for sliding glass patio doors with worn rollers but the sliding glass door track is in good shape. If your roller rail has bumps or dips in it, IT IS RECOMMENDED to also purchase a one section, 8 foot 1/4 inch roller rail cover so the "Slide Guides" have a straight, smooth surface to ride on.
Kit will repair one door up to 8 feet in length and includes all installation hardware.
