Westcott Rapid Box Octa-S with FJ400/Bowens Insert Softbox

The Westcott Rapid Box Switch Octa-S is a 26-inch collapsible octagonal softbox built for photographers who need professional-quality light modification without the bulk and setup time of traditional softboxes. Its umbrella-inspired aluminum framework allows it to open and close in seconds—simply slide the shaft, lock the collar, and attach your diffusion panel. The reflective silver interior directs a specular pattern of light that wraps around subjects with pleasing contrast, making it well-suited for portrait, headshot, and product photography in both studio and on-location settings.

Central to the Rapid Box Switch system is its interchangeable mount design. This bundle includes the FJ400/Bowens S-style mount insert, which attaches to the rear of the modifier and locks securely in place. Photographers who work with multiple lighting systems can purchase additional Switch Mount Inserts for other strobes, speedlites, or monolights, turning a single softbox into a cross-platform tool. The construction features an all-metal locking collar and eight metal ribs, backed by Westcott's one-year warranty. A premium unbleached nylon diffusion panel and a travel case complete the package.
