These are Fully Telescopic Linear Guides made of cold draw steel rail materials.  The DEF43 telescopic linear guide has a cross section approximately 43 mm ( 1.69") high x 44 mm  (1.73") wide, basically a square cross section.  One side of the assembly attaches to your structure while the other side attaches to your moving drawer.  These are typically used in pairs, one on each side of the moving drawer. 

Load rating is per slide assembly.  Each assembly utilizes two retained ball bearing sub assemblies for almost frictionless movement of the rails.  Rail holes are drilled and tapped for an M8 threaded fastenerRail holes are spaced every 80 mm (3.15") along the length of the each rail.
