impact LS-CL40M Series 40 Inch C-Stand with Quick Release Sliding-Led Instructions

impact LS-CL40M Series 40 Inch C-Stand


Thank you for choosing Impact

Impact’s C-stand features a 40-inch double riser. The C-stand is constructed with oversized steel tubing for maximum rigidity and strength to hold light fixtures and accessories up to 22 pounds. This sliding-leg model has a movable top leg that’s designed for leveling the stand on uneven surfaces like stairs or a curb. Impact’s unique quick-release leg lock simplifies opening and closing the legs for rapid deployment and breakdown. Three leg heights make it possible to soldier these stands closely together for convenient light placement, transport, and storage.

  • Always make sure the load is supported when loosening any of the riser knobs to adjust the height of the stand
  • Make sure the load is balanced.
  • When handling a kit (grip head and grip arm mounted on top pin), always grab the riser and grip arm together to prevent your hand from catching between the arm and the main riser.
  • When opening and closing the legs, make sure the area around you is clear. Be especially aware of the perimeter where the legs swing open and closed, as well the other end of the center column.
  • When opening the legs, make sure the sliding leg is locked in with the bottom two legs. If the sliding leg is not locked in, it can slide up the center column, and the legs won’t open. If this happens, you can manually adjust the sliding leg to lock it in place, and then open the legs.

Using the Sliding Leg

The sliding leg adjusts the C-stand’s vertical alignment on an uneven surface like a hill, stairs, or curb.

  1. Loosen the sliding leg’s locking knob.
  2. Adjust the height of the sliding leg so the main shaft is vertically aligned, and tighten the locking knob until secure.
Attaching the Grip Head

Loosen the locking handle, and place the grip head’s baby receiver over the baby pin. Then tighten the locking handle until secure.

Attaching the Grip Arm
  1. Face the grip head’s T-handle, and loosen the T-handle.
  2. Make sure the 5/8-inch hole is on top of the T-handle. Insert the grip arm with the load to the right of the grip head.
  3. Tighten the T-handle until secure.

Important! Make sure the T-handles faces you, the arm is inserted through the top of the grip, and the load is on the right side of the T-handle. This will prevent the T-handle from accidentally loosening.
