Please note that the load capacity data are for the pair of guides installed with their narrowest side perpendicular to the ground on the sides of the element to slide. When the guides are installed flat under the element to slide, the load capacity is reduced to approximately half. It is very important to take into account the separation that must exist between the side of the drawer and the side of the cabinet to allow it to function properly. The average separation distance of the drawer from the side of the cabinet is 13 mm on both sides and fastened with countersunk head screws.
