Overview
The Lightsock Replacement Tightening Knob (LSKNOB) is the standard M5 fastening knob used across the traditional Lightsock covered wagon lineup, including the LS20, LS40, LS80, and all Dooplo 20, 40, and 80 systems.
Often referred to on set as a “tie down,” this aluminum M5 knob secures the end plates directly to the Astera tube. It provides tool-free installation while maintaining a clean, professional interface consistent with the original Lightsock hardware.

Usage Notes
Single-tube Lightsock systems use two knobs per unit (one per end plate). Dooplo dual-tube systems use four knobs per unit (two per end plate).
To avoid cross-threading, ensure the end plate is flush and aligned before tightening. Secure firmly by hand; over-tightening is not required.
