Why isn’t there a locking knob on the boom pivot?

Unlike traditional booms, no phyiscal brake is necessary, as the load of the fixture is balanced by rear counterweights. A properly balanced light boom will retain its position, and can be fine tuned by sliding the rear counterweights forward and backward.

When removing a fixture from the boom, we recommend removing the rear counterweights first and resting the light in a boom-down position. Removal of the fixture first, could cause the boom to unexpectedly pivot upwards.
