speedring

A speedring is a circular mounting ring used in photographic and film lighting to attach a softbox or other accessory to a light source. The ring forms the front frame of many softboxes and provides the mounting interface to the matching light-head standard, such as Bowens, Elinchrom, or other proprietary systems. Some softboxes include a speedring as an integrated, replaceable component that allows the same modifier to be used with different light brands by swapping rings.

Speedrings are typically made from aluminum or durable plastic. They are circular with a central hub and outward-facing mounting tabs or slots that align with the softbox fabric or diffuser. The inner circumference holds the fabric and diffuser, while the outer edge attaches to the light or to a mounting plate. Many designs use a quick-lock mechanism to snap the ring onto the light for rapid setup.

Compatibility can vary by brand; common types include Bowens-style and Elinchrom-style rings, with some rings universal or available as adapters to fit different lights. When purchasing a softbox, check that a matching speedring is included or that an optional adapter is available.

To use, align the ring with the light head, engage the locking mechanism, and secure the fabric over the frame. Avoid over-tightening and store the component in a cool, dry place to prevent warping. Inspect regularly for bent tabs or frayed fabric.
