3/8" Dia Pella Set Screw
Product Code: 84-510
Replacement Pella set screw, measures 3/8" in overall diameter x 1/2". This is a genuine Pella part.
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.
