In the milling process of each custom order, we produce additional workpieces to ensure the accuracy and precision of the bar joinery. Over time, we accumulate a collection of test bars, which we assemble into complete stretcher sets and sell at a reduced price. All Test Stock stretchers adhere to our milling and straightness standards. They may have minor cosmetic imperfections, like slight scratches or small, solid knots. We ship all Test Stock stretchers as unassembled bars via UPS.
