Century Stands or "C" Stands, are the most common type of grip equipment used by the film making industry due to their strength and durability. The Kupo Master 40" C-stand can be used to mount everything from a speed light, through to large, powerful studio lighting and modifiers. The Kupo 40" Silver Master C-Stand has a patented spring ring locking system in the base that removes tension from the legs so that gravity can do the work for you. "Turtle-base" is an industry term where the riser section can be quickly removed from the base for easy transport. The base can also be used with a stand adaptor for a low mounting position.
