STKIT Assembly Instructions
CAUTION: Before assembling the Seat Track Channels to the loudspeaker enclosure, note
that the kit is supplied with both 3/8-16 Unified Course and 10mm Metric fasteners. These
fasteners are very similar but they are NOT identical. It is critically important that you use
fasteners with the proper thread pitch. All S- Series loudspeakers use the M10 metric
fasteners. DO NOT USE THE 3/8-16 UNC FASTENERS! It is very easy to mistake one
thread pitch for the other.
1. To assemble the Seat Track Channel to the loudspeaker enclosure, first remove the
factory supplied flat-head Allen screws from the top of the enclosure.
2. Next, place a Seat Track Channel over each rigging fitting in the enclosure. Orient the
Seat Track Channel so that it is not overhanging the edges of the enclosure, and align
it so that it’s parallel to the enclosure side (see Figure 15). Using a fastener with the
proper thread pitch, thread each fastener into the rigging fitting in the enclosure until it
is finger-tight. If a fastener does not thread easily into the fitting in the enclosure, it
may be of the wrong thread pitch. Do NOT force it with a wrench! Check the threads
to make sure they are correct. You can do this by comparing the supplied fastener to
the one that you removed from the enclosure. If the threads are identical, you will not
be able to see any light between them when they are nested together. If you can see
any light at all between the two fasteners when the threads are placed next to each
other, they are not identical!
DANGER: Use of the wrong threaded fastener will result in thread failure under load, which
can cause damage to property, serious injury, or death.
3. Tighten each fastener to a torque of 15 foot-lbs using a torque wrench. Do not
overtighten.
Note: Allen wrenches with 3/8” and ½” socket fittings, designed to attach to a ratchet
or torque wrench, are readily available at tool stores.
4. Now, using an electric screwdriver, insert one 8 x 1” flathead Phillips screw into each of
the small holes in the Seat Track Channels. Tighten until snug. Be careful not to
overtighten, as the screw will break under too much torque. The purpose of these
smaller screws is only to keep the Seat Track Channel from rotating under load.
5. After attaching appropriate mating hardware to the Seat Track Channels, you can now
lift the enclosure a foot or two off the ground. Check to make sure all fasteners are
tightened securely, and then bring the enclosure to trim height.
Using More Than One Enclosure
Additional Seat Track Kits may be used to suspend one enclosure over another. This is
accomplished by attaching one set of Seat Track Channels to the bottom of the upper
enclosure, and a second set of Seat Track Channels to the top of the lower enclosure.
The two enclosures may then be joined together by using various hardware fittings that
mate to the Seat Track. Such hardware includes swivel fittings, tandem swivel fittings, and
other mating devices that are readily available from theatrical rigging suppliers.
CAUTION: Be sure that all mating hardware used to suspend the enclosure(s) is
specifically rated for overhead use and capable of supporting the weight load of the
enclosure(s) with an adequate Safety Factor. Some hardware fittings are NOT rated for
overhead use, but look very similar to those that are. Check with the manufacturer or
supplier to be sure.
If multiple enclosures are suspended one above the other, it is the installer’s responsibility
to insure that the combined weight load does not exceed the 100 lb Working Load Limit of
any one rigging fitting. This is particularly important if the enclosures are angled
downward, as most or all of the weight will be supported by the rear points only.
