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.
