This tray was a touch larger in size than I expected on outside dimension so it didn't fit my also inexpensive add-on plastic battery box from Amazon. I had to size it down and re-weld it which ruined the beautiful plastic coating on this tray, but for the money I couldn't find a metal tray to fit perfectly inside the battery box but I made this one work. For all open applications, it's worth the money and should last the life of the vehicle.
