Hiwin bottom mount "T" type rail

Rail that has a "T" designation is smooth on the top and mounts via Threaded holes located on the bottom of the rail. This type of rail is available for many sizes of both AG and LG. See chart below for specifications. Please pay particular note to the "E" and "P" dimensions. On uncut factory rail, the "E" measure is the distance from the end of the rail to the center of the first mounting hole. This can be a critical point if you are replacing an existing rail section. The "P" dimension is the mounting hole center-to-center measure.
