The most commonly used wrench size for tray work is?

Explanation:
In tray work, the wrench size you reach for most often matches the hex head size used on the majority of tray hardware—fittings, supports, and channel bolts. A 9/16-inch wrench fits the common hex heads on these components well, giving enough leverage to snug fasteners securely without being so large that it won’t fit in tight spaces. This widespread compatibility across many tray parts makes 9/16 inch the standard pick for daily tray installation and maintenance. Smaller sizes like 7/16 or 1/2 inch are used on lighter hardware, while 5/8 inch is reserved for heftier bolts, so they’re less routinely needed in typical tray work.
