The grid hinges must be installed with the hinge bases located at the outside of the track towards
the sides of the enclosure as shown in Figure 5 with the locking pins on the fittings located next to
the sides of the enclosure.
To install an Xvhp pick-up hinge into the track of an enclosure, grasp the hinge base and firmly
insert it into the long cutout in the track, pressing in until the spring-loaded locking pin is fully
retracted. Then apply pressure to slide the hinge base sideways towards the end of the track until
the spring-loaded locking pin drops into the hinge-locking-pin hole in the base of the track. Once
the locking pin is fully engaged, the grid hinge base will be immovable in the track.
ALWAYS CHECK TO MAKE SURE THAT THE PICK-UP HINGE BASES ARE
INSTALLED IN THE CORRECT ORIENTATION WITH THE HINGES AT THE
OUTSIDE EDGES OF THE TRACK. ALWAYS CHECK TO MAKE SURE THE
PICK-UP HINGE BASES ARE SECURELY LOCKED INTO THE TRACK, AND
THAT THE LOCKING PINS ARE FULLY ENGAGED IN THE TRACK BEFORE
LIFTING ANY LOUDSPEAKER ENCLOSURES OVERHEAD.
To remove the Xvhp pick-up hinge, grasp the locking-pin knob and pull out while applying
pressure on the hinge to slide the hinge base toward the long cutout at the end of the track. The
hinge base will come out of the track once it is aligned with the cutout. For added safety, the
locking pin has a special shape that engages with the track to prevent it from vibrating out of the
track hole during use. If the locking-pin knob seems difficult to pull out when removing the hinge,
wiggle the hinge base while pulling out on the knob. When the hinge locking pin is centered in the
track hole, the pin will easily release.
1.4 Front Rigging Strap Details
The Xvsg, Xvsl, and the Xvsd chain rigging strap, shown in Figure 4, are identical except for their
length. Figure 4 shows the X-Line external rigging hardware details and key dimensions.
Xvsg Grid Strap:
Two Xvsg grid straps are used to attach the front of the top enclosure to an
X-Line-compatible grid. Each grid strap consists of two rigging fittings connected by an alloy-steel
chain. The Xvsg has the shortest chain of the three front rigging straps to minimize the space
between that the top enclosure and the grid. Each fitting is a proprietary triple-stud fitting that has
a large steel locating plunger. The plunger not only locates in the round cutouts in the track, but
also extends into the base of the track for extra strength.
To install the Xvsg triple-stud fittings in the enclosure rigging track, grasp the fitting with one hand
and pull the spring-loaded safety locking pin out with your free hand. Continue to pull until the
locking pin retracts above the three stud feet of the fitting. Insert the three round feet on the end of
the fitting into the round cutouts in the track and slide the fitting to the desired position. Center the
locking pin of the fitting over one of the track cutouts. Release the locking pin. The pin should
extend beyond the bottom of the fitting and should lock into the round recess in the base of the
track with the locking pin retracting to its normal position. If the pin does not lock into the base of
track, nudge it along the track and wiggle as necessary until it settles into position. When locked,
the fitting will be immoveable in the track. The user must be careful not to insert a twist in the
chain when installing the second end. A twist will result in the grid hinge assembly being shorter
and will introduce excessive forces in the chain.
