Powerdyne Adjustable Round Stops - Black
Price in GBP
These will fit most plates that require adjustable stops
Note: Adjustable stoppers don't come loose from vibration so require little maintenance. Removing the stopper or adjusting the height is simple - just loosen the lock nut located on the base of the toe stop bolt, then unscrew the stopper by hand to adjust the height or to replace it. Make sure you tighten the lock nut properly again or it will fall off while you're skating! Check lock nut tightness occasionally.
