Roll-Line Tube Wrench

The Roll-Line TUBE WRENCH 11mm - 17mm is used to simply Tighten or Loosen the Action Adjustment on Roll-Line Click and Non-Click Skate Models, with the 17mm end of the Tube Wrench to adjust the amount of action desired.Keeping the King Pin Locking Screw Tight is very important to the safety of the Skaters. The King Pin Locking Screw is also known as the "KEEPER Screw", (which loosens with the 4mm Allen Wrench) as it keeps the Adjustment Nut from being able to be backed off to the point that the skate will come apart, while skating. If the King Pin Action Adjustment Nut or Click Nuts are loosened (to achieve more flexible Action) to the point that they hit the "Keeper Screw", the Action has been Loosened to the maximum of its adjustment range. This is based on the Suspensions (Cushions) that you are using. If you need more Action, a more flexible Suspension (Cushion) will be required, to allow the Skate Adjustment to be operated in the normal operating range of the adjustment. The Normal Operating Range, Does NOT include backing out the "KEEPER Screw" to achieve a more Flexible Action. The 11mm End of the TUBE WRENCH used to Tighten or Loosen the Metric Axle Nuts. This handy L Shaped Tube Wrench is very easy to use.
