SKU I9W7H3V5
These screen door rollers are designed for smooth, long-lasting operation on sliding screen doors, especially models from the KDEX20 series and other compatible brands. Each roller features a 1-1/4 in. steel ball bearing and an integrated wire tension spring to maintain consistent tracking and reduce friction. The set includes four identical units, intended for simultaneous replacement on a single door panel—two at the top and two at the bottom—to ensure balanced movement and prevent misalignment. Constructed with heat-treated bearing steel, they resist wear far better than untreated carbon steel alternatives, supporting reliable performance through at least 100,000 operational cycles. The rollers mount easily using standard hardware and fit common track profiles without modification. They help eliminate dragging, sticking, or uneven rolling caused by worn-out components. No special tools are required for installation, and adjustments can be made by hand to fine-tune door height and tension. Regular maintenance involves only occasional cleaning of the bearing surface and track to preserve smooth motion over time.
