Whether the slides are intended to hold a drawer, door, component, or chassis, the width of the pull-out unit has a large effect on performance. If the slide does not have the strength and load capacity that corresponds to the width, it can cause racking or side-to-side movement. Excessive racking causes instability and can result in drawer failure.
Take note of the maximum recommended drawer widths for the slide products you are considering. When widths are 24" or greater, adding stability by using a slide with a larger cross section and a higher load rating is often the best solution.
