Each Pendulum Holder has its own knurled thumbscrew and locking device that holds each individual chord for easy adjustment without disturbing the other pendulums. 

Sturdy Pendulum Clamp has an all steel bracket that allows for up to 3 pendulums to be suspended at one time without any wobbling. 

The bracket is attached to a rod clamp that is tightened with a large knurled knob.
