The pigeon Stand with 5/8" Spigot Kit was put together to facilitate low-angle lighting or shooting. The kit comes with the flat-folding backlight stand and a spigot with male 1/4"-20 threads on one end and 3/8"-16 male threads on the other. The stand, when closed, folds flat into one piece of 13.25"-long steel. In use, the legs fan out to form a base with a stable footprint of 20". The exterior of the spigot measures 5/8", which is an industry standard size for mounting most light fixtures. The threads at each end of the spigot allow you to screw on accessories that have female 1/4"-20 or 3/8"-16 threads.
