Product Description
This sliding screen door replacement roller assembly has a two piece plastic roller housing with a 7/8" nylon center groove wheel and a spring loaded adjustment screw. Sold individually

Good Idea!
The typical patio sliding screen door uses two roller assemblies, one on each bottom corner of the sliding door. We recommend replacing both sliding door rollers at the same time to prevent extra wear-and-tear to one new roller, which will have to work twice as hard when paired with an old roller.
