Practical adaptor for a quick and secure flying of Line Array systems using ULK lifting towers. 

(Check the maximum load capacity of the tower) 
The adaptor is fitted and raised in the following way: 
1. Insert the adaptor onto the ULK forks. 
2. Tighten the securing knobs of the adaptor until you achieve a perfect fit to the forks. 
3. Once the adaptor is properly secured to the forks fit the Line Array system to it. 
We make adaptors for both 50 mm and 60 mm forks.
