Stands to hang your heating equipment from are really useful for open top enclosures, such as tortoise tables, but can also be used for mesh top enclosures, where you wouldnt want the heat source touching the top of the unit. These offer you a flexibility with the height at which you have the heat bulb, and also the area that it hangs over, as they can be easily moved around as well as up and down, so you can get the perfect hot spot.
