Kupo S401212 3-Section Wind-Up Stand with Auto Self-Lock

The Kupo Wind-up stands have been the definition of strength and safety in the grip industry since their inception. They enable a single operator to raise and lower heavy loads safely with just the turn of a handle. As you crank the handle both risers move simultaneously. A single clockwise revolution of the handle raises the stand 1.73" (4.4 cm) and a single counter-clockwise revolution will lower the stand by the same amount.

The S401212 has an automatic self-locking mechanism that prevents the light stand from dropping unexpectedly making the operation safer. The risers have a series of perforations that are engaged by a safety pin. With the auto-lock engaged, the safety pin automatically locks into each successive perforation as you raise the stand.

Once the auto-lock is disengaged, an internal spring retracts the safety pin allowing you to lower the stand. The crank handle folds back for travel. It also is designed as a safety measure and can be folded back and placed between two of the tripod's legs. The reason for this is to catch the handle and prevent it from turning, stopping the risers from quickly falling if the lock is unexpectedly disengaged.

The tension between the brake shoe and risers is user adjustable, simply with an Allen wrench. The S401212 also features a leveling leg that enables the user to extend one leg more than the others to level out the stand on an incline or uneven terrain. The S401212 comes equipped with a skid-proof foot-step located on the main section of its base to allow the user to stand upon it to reach the top risers and head to make adjustments if necessary.
