Single-wheel rollers moulded in black nylon housings with a choice of green or orange concave wheels and a captive Phillips adjusting screw. The plastic body dampens noise and cannot rust, while the concave wheel self-centres on round tracks. Turning the screw changes ride height to compensate for worn rails or uneven floors. Lightweight and tool-friendly, these suit aluminium sliding windows and shower doors; available in various sizes.
