This adjustable roller combines a white nylon concave wheel, a zinc plated steel yoke and a robust black nylon outer body. A large Phillips-head screw projects from the end, giving quick height adjustment with a standard driver. The concave profile cradles round tracks to prevent lateral wander, and the plastic shell insulates against rattling. Designed for sliding window sashes and wardrobe doors; available in various sizes.
