Pairing high-end fabrics with a quick-collapse frame, our Rapid Box modifier series will give you the professional results that you want without the tedious setup. We purposely designed the Rapid Box with an external cold shoe speedlight mount. By keeping your speedlight outside of the softbox, you can quickly access controls and utilize the IR line-of-sight (or infrared wireless) functionality commonly found in speedlights. Of course, radio triggers can be used as well.
