This 40" C-Stand Sliding Leg Kit with 2.5" Grip Head & 40" Grip Arm from Lowel, in a chrome finish, incorporates lighting industry-standard features and build quality that will perfectly fit grip trucks or C-stand hangers for convenient setup, transport, and storage. The staggered leg height design allows nesting several stands closely in tight spaces, without taking up much floor space. The sliding top leg is designed to level the stand on uneven surfaces like stairs, hills, and curbs.
This kit pairs the stand with a 40" grip arm for supporting light fixtures and light modifying gobos like flags, silks, and scrims. In addition, there is a 2.5" grip head which provides 5/8" and 3/8" holes for mounting grip arms and other lighting fixtures or grip equipment.
