NOTE: DURAFLEX REPAIR

KIT 30052

Suspending this system should only be done by qualified persons following

safe rigging standards.

Remember: the weakest component determines the size and safety of the

entire array! CAUTION! Before suspending any array always inspect all

components of the array (enclosure, truss module, threaded fasteners,

connecting hardware, and lifting hardware) for cracks, deformations, corrosion,

missing or damaged parts that could reduce strength and safety of the array.

Use only load rated hardware. Building structural supports and hoist motors

require inspection prior to each use by knowledgeable professionals. Never

exceed maximum recommended load ratings.

In the event that the track has suffered damage, replace only with the correct

part (see below) from JBL professional. Replacement with parts from other

sources may result in suspension failure.

Track 3” fly ware part number 390-00012-00

Track 8” fly ware part number 390-00013-00

The only fitting load-rated for over head use is a SMI (909) 878-9104 part

number SM-61B “L” Double Indexing locking Swivel Ring Fitting or a ATM

(310) 834-5914 part number AMTS-3SF.
