This stand has a special setup with two legs that automatically open and lock in place due to spring-loaded mechanisms. The third leg is adjustable in height by loosening a locking knob and sliding it along the main riser section. This flexibility allows you to raise one leg higher than the others, making it useful for stabilizing the stand on surfaces that are not flat, like slopes or uneven ground. This feature ensures the best possible support for your light heads, reflectors, and gobos, keeping them steady and secure.
