The Telescoping Crossbar can be extended between 224cm and 400cm and is therefore far ahead from other pluggable systems. You can mount the crossbar on every 5/8 inch spigot (e.g. lamp tripod, super clamp and so on). Thus, this item provides multiple ways of usage! Tip: In connection with Autopoles, the Background Crossbar is a perfect help in the daily work in studio.
