Why You Need C-Stands

C-Stand Tops with Brake Castings

Century Stands, or C-Stands as they are most commonly called, are the quintessential multi-tasker when it comes to a piece of grip equipment that can be used for so many applications that are only limited by the imagination of the user!

C-Stands get their name go back to the pre-electric days of film production where the studios would use rotating stages to utilize the daylight coming from above and redirect it with large 100″ “century” sized reflectors to redirect the light where it was needed.

C-Stands are have a unique base where their three legs are each a different height. This enables you to place two stands just inches away from another to allow you to place lights and or accessories in close proximity to one another. Other lightstands with angled legs are really limited to how close they can get to one another. This ability to place one right next to the other is sometimes referred to as “soldiering” as soldiers would line up in formation.

Their are two types of C-Stands, Turtle Base & Sliding Leg. Turtle Base stands allow you to remove the riser section for easy transportation, storage and the ability to place light fixtures, modifiers and accessories at super low mounting positions just above the base.

Sliding Leg stands allow you to alter the height of one leg to help you level your stand on inclines, stairs, or uneven surfaces.

This is not your daddy’s c-stand! Anybody who’s tried to open or close a c-stand may have had some difficulty, especially if they are not well maintained. Professional grips do this day in and day out and make it look simple. Kupo has come up with an ingenious solution to open or close our turtle base models in under a second! Check out this video!

Their height are described by the length of the riser section. C-Stands come in either 20″ or 40″ double riser models. Just triple the number (the main riser section plus the two adjustable riser sections) and add the base height to get an idea of their total height.

Obviously these stands can hold lighting fixtures, but with standard accessories such as Grip Head & Grip Arm, these stands become:

  • Reflector Holders
  • Background Holders
  • Gobo Holders
  • Prop Holders
  • Camera Support
  • And a whole lot more!

Other advantages of c-stands besides the ability to “soldier” up next to other and their awesome multi-tasking flexibility are:

  • They are made of solid steel, won’t fall apart and will last you for decades!
  • They can hold more weight than light weight aluminum kit stands.
  • They won’t crush or bend like aluminum stands will.
  • For Turtle Base models, the base removes for easy transport and storage as well as you can mount adapters directly into the base for low mounting positions.

Some grips joke that c-stands got their name because it will take a century to learn all the ways to use one. Buy one (or several) today and you’ll have a reliable multi-tasker that will serve all your imaging needs until your c-stand develops a history all its own!



C-Stand Double Riser Sections

40″ Riser Section (KS742412)


Kupo has three different sizes of Century or C-Stands: 20″, 30″ & 40″. To clarify what these numbers mean, this is the length of the riser section when it’s completely collapsed. Since all C-Stand riser sections are double risers, this means that there are a total of three sections, The Main Riser Section, the first riser section and the second riser section. So in essence if you multiplied the length of the riser section by three and added the heigh of the base, you would come to the total height of your C-Stand.

One of the many advantages of the Turtle Base C-Stands is that the riser sections are removable. Say you purchases a 40″ Double Riser Stand and you it is too tall for your current application, if you didn’t want to purchase a complete 20″ C-Stand, you can always just purchase the just the 20″ Riser Section, thereby saving you money.
