This is a replacement blackout sider for the Lightsock Dooplo 20, a dual-tube covered wagon modifier designed for use with two Astera Helios Tubes.
Each Dooplo 20 kit normally includes two blackout siders, which attach with Velcro to the sides of the pearlescent diffusion panel to help block spill and control light shape. This listing includes only one replacement sider—ideal if an original has been lost or damaged.
The sider is made from durable blackout fabric and installs quickly using the same hook-and-loop system as the original kit component.
⚠️ Note: This is not a complete Dooplo 20 kit. It includes only one blackout sider.
