ceiling truss or any structure capable of taking 3Kgs (7lbs) this includes the weight of
a ceiling tile.

Attach the supplied safety harness hook to the eyebolt on top of the C 303 metal
case and insert the free end of the cable through the entrance hole on the gripper.
Attach the other end of the safety cable to a fixed secure structure.
