This adjustable sliding window roller pairs two concave blue nylon wheels with a sturdy galvanized steel channel housing. A threaded adjuster at the base raises or lowers the axle to fine-tune door height and compensate for track wear. The nylon wheels roll quietly over aluminium tracks, while the tandem layout spreads the load for smoother, more stable gliding. Suitable for aluminium sliding windows and doors; available in various sizes.

- Twin blue nylon concave wheels for quiet, low-friction travel
