Encased in a black nylon shell, this tandem roller uses twin green wheels on a steel axle with an internal compression spring. The closed housing keeps dust out of the raceway and simplifies retrofitting into aluminium door bottoms. Green wheels grip the track smoothly and resist flattening under sustained weight, and the spring-backed axle self-adjusts as the door settles. Ideal for sliding wardrobe doors and aluminium window frames; available in various sizes.
