Featuring a rubberized hand grip, the Elinchrom EL-Boom Arm 63-156cm is ergonomic and extremely easy-to-use. It lets you extend lights up to 5.1 feet and offers a more precise, flexible way to position your lights even if they are attached to umbrellas or softboxes. The boom arm is more convenient to use than a regular stand as it takes up less floor space. It can approximately hold accessories weighing up to 4.4 lbs (2 kg). The boom arm is compatible with Elinchrom flash heads and Ranger Quadra heads.
