Featuring heavy-duty chromed-steel construction, the Mini Baby Double Header from Matthews presents the capacity to mount four light fixtures on a stand with a "Baby" 5/8" top stud to save floor space. The accessory has four 2.25" long 5/8" pins with anti-twist knurling: two (upper and lower) at each end of the 9" long central support bar. The Header has a 5/8" receiver for the light stand.
