7.2 - VTX A12 - ANGLE-LOCK MECHANISM 

VTX A12 includes an innovative Angle-Lock mechanism that automatically engages when the cabinets are suspended and reach the 

desired angle position. The Angle-Lock mechanism consists of two main parts, the RED 

LOCKING LEVER

 and the black 

RELEASE 

BUTTON

.   

The system is 

locked

 when the RED locking lever is recessed 

into the cabinet. When the cabinets are suspended, a sequen-

tial locking sound is audible that indicates that the system 

reached the final position and is locked. The system will remain 

locked until the Angle-Lock mechanism has been released.     

LOCKED POSITION

When it’s time to de-rig the system, the Angle-Lock mechanism 

is released so that the cabinets can collapse again and be set 

on the VTX A12 VT at 10-degrees. Press the release button to 

unlock the mechanism. 

When the button is pressed, the RED locking lever is released 

and moves to the unlocked position. The RED locking lever is 

spring loaded and will maintain its position until the user man-

ually changes the mode. The Angle-Locks are set to the unlock 

position until the cabinets are  attached to the VTX A12 VT and 

collapsed all the way to 10-degrees. 

NOTE:

 The RED Angle-Lock levers are used to secure the angle 

position and prevent the cabinets from taking a different angle 

when cabinets are deployed in an array. The RED Angle-Lock 

lever is not load-bearing and the system is safe even if they are 

accidentally left in the unlocked position.
