Rail length is 350 mm (13.78 in) and the carriage block measures 45.7 x 27 x 10 mm (1.80 x 1.06 x 0.39 in). Made from 440C stainless steel, it offers higher hardness and corrosion resistance than standard bearing steel. The carriage features four M3 threaded holes (4-M3x3.5) with a 20x20 mm center spacing; rail holes are spaced every 25 mm along the length. Two rubber stoppers at the ends prevent derailment.
