The Big Bar Stop was created specifically for holding parts in Kurt 3600V, Kurt II  as well as several other machine vises as thin as 1/8" of an inch with no interference from the part stop.  Designed with versatility in mind it can perform many duties and is only limited by the imagination.  Fits between vises spaced 1" apart on the machine table.  It's also machine-able for custom applications. Comes with vise mounting bar, stop bar and strap stop with screws.  Also available, a 3 pack of the strap stops for additional setups.
