This system is rated with a 23.6 in (600 mm) center width, which defines the maximum specimen length that can be supported between centers for round tensile specimen preparation.
In day-to-day use, the practical usable length depends on how much stock you need to keep engaged in the chuck or clamping fixture for rigidity, and how much tailstock support and tool clearance your specific specimen geometry requires.
If you are preparing threaded-end or button-head tensile bars, plan extra allowance beyond the finished specimen length for facing, center work, and secure workholding so the gauge section is machined without chatter or slippage.
