Commonly used sliders have two types: flange type, and square type. The former is a little lower，but more wider, and the mounting hole is a threaded hole, while the latter is a little higher and narrower, and the mounting hole is a blind thread hole. Both have short type, standard type and elongated type, the main difference is that the length of the slider body is different, of course, the hole spacing of the mounting hole may also be different, most short type slider only has 2 mounting holes. The number of sliding blocks should be determined by the user through calculation. Generally, we only recommend one: as few as can be carried and as many as can be installed. The type and number of sliding blocks and the width of sliding rails constitute the three elements of load size.
