SKU R5O4J0S1
These tandem rollers are engineered for smooth, long-lasting operation on sliding glass, screen, and patio doors made from wood, aluminum, or vinyl. Constructed from galvanized alloy steel, they resist rust and corrosion in humid or outdoor environments while supporting up to 330 lbs. per pair. Their universal design accommodates most standard extruded aluminum and vinyl door frames without requiring specialized tools for installation. Replacing both rollers simultaneously is recommended to ensure balanced movement and even weight distribution. The compact housing and precision ball bearings reduce friction and prevent binding during lateral motion. Dimensions match common OEM specifications, making them suitable for retrofitting older door systems without frame modification. They operate quietly and maintain consistent alignment over time, minimizing wear on tracks and door edges. No lubrication is required during normal use, and the sealed bearing assembly protects internal components from dust and moisture ingress.
