Bogen Master - Brand: Win-Vic - Model Name: Bogen Master - Category: Ski Accessories By attaching this to the tips of your skis, the skis will not separate or overlap, naturally forming the snowplow position. This is the perfect item for children who are new to skiing. Used only once. I am selling it because I have no opportunity to use it. ■ How to Install 1. Attach the Bogen Master to the tips of the skis, at a suitable position inside the middle, and tighten the screws firmly. 2. Align the skis parallel (with a fist-width gap in the middle), make them symmetrical, and attach and tighten the other screw. ※ For safety, the joint part is designed to separate if excessive impact is applied, such as from a fall. If it comes off, you can re-set it.
