The stabilizer is made of fiberglass reinforced plastic and serves to affix the runner to the holder. It consists of a screw and nut side, which are connected using a system key. 

Advantages:

• Quick & Easy Runner Exchange
• Fail-proof screwing parts
• Stable connection between holder & runner

Use:

Loosen all the screws using the key.  Then, press the key with the screws to detach the against groove side of the stabilizer. Take off both sides (nut and screw side) of the stabilizer.

After swapping out the runner, push the groove side into the holder first. Then attach the screw side of the stabilizer and fasten the screws.

Please note that for an easier mounting and dismounting, the screw side of the stabilizer should always be on the inner shoe side.
