Suspending the WideLine-8 Array

Pull-Back Bar

To use the pull-back bar, attach it to the bottom enclosure’s suspension

plates using one of the lower sets of splay angle adjustment holes.

Align the pull-back bar’s holes with the suspension plate’s and fully

insert the ball-lock pins. Ensure locking action of pins. Use a 5/8” (16

mm) screw-pin anchor shackle to attach to the pull-back bar as required

using the shackle holes.

NOTE: All hardware/components must be rated for the

expected loads as determined by the Professional Engineer

responsible for suspension.

NOTE: The PB3082 can also be used to suspend small arrays

of WL3082 enclosures. See page 10 for detailed information.

Extension Bar

The extension bar suspension plates can be moved, if required, by

removing the two 3/4”mounting bolts, moving to the selected mounting

location, and reattaching. Tightening torque is to be 100 lb-ft of torque

(135.6 N-m) Ease-Focus software’s center-of-gravity calculator will pro-

vide a suitable point for desired down-tilt.

Attach the array frame to the extension bar suspension plates by

centering the array frame member between the extension bar sus-

pension plates and bolting together using the supplied 3/4” bolts.
