Hello! I came across this site and it got me thinking about using these fittings for a garage work bench. Any assistance/ideas you guys have would be appreciated. The overall width would be 13 feet with a depth of 28 inches and a height of 3 feet. I would not be putting a lot of weight on it but want it to hold up to the rigors or misc projects. I am concerned about bracing it properly at that width. At the end of the day I want to make something that is structurally sound. Thanks in advance for any suggestions you guys may have.
