RaceWax World Cup Pro Ski Vise All Metal Three Piece Heavy-duty, all-metal construction. Jaw opens up to 105 mm. Can take wider skis if you simply clamp to the binding (instead of the sidewalls) - it is faster and easier! 50 mm wide gripping length on center jaws (this is the length of the black grip seen on the center jaw) offers superior stability for skis. Height adjustable end supports that are spring loaded. End supports rotate to offer ergonomic angle options. The clamps that fix to the tuning bench open to 2.25 (standard for all brands of vises). Add snowboard adapters to convert for snowboard or Nordic tuning; open the end support screws fully, place the adapter in, then tighten.
