This FlexiArm from Dot Line is 22" long and supports small lights, reflectors, flags and other items up to 1 lb. With a double stud and 5/8" spigot receptacles at both ends, it is a versatile support for use in studio or on location. Made of flexible aluminum alloy, this 16mm diameter arm can be shaped into configurations that would be impossible with a jointed articulating arm. These FlexiArms feature removable 5/8" spigots that are reversible with both a 1/4" threaded stud and a 3/8" threaded stud.
