In this video I show you how I built this tool storage unit for around $40 using ball bearing drawer slides from Amazon and scrap wood laying around the house. I designed it to hold gauge pin set boxes but you can easily customize it to hold any sort of tool box or tray. It can support the 30 pound boxes without a problem and fits perfectly on my shelving unit. Buying a similar drawer unit would have cost me hundreds of dollars so this DIY solution was the perfect answer.
