In the packet you will have the ice grip ferrule and two sets of screws, one long and one short.
1. Unscrew the screws and fit the ice grip around the tip of your walking stick so that the spikes fit under the existing rubber or steel ferrule.
The spikes should now be touching the ground.
2. Now tighten either the long or the short screws supplied, whichever fits according to the diameter of your walking stick.
3. When the spikes are not needed, squeeze the white handle together and turn the ice grip upside down so that the spikes are pointing up towards the stick handle and are flush against the stick shaft. Then release.
