XT-BT1203 BLK

The ProX XT-BT1203 BLK is a 3 ft bolted 12" professional box truss segment with a 3mm wall, part of the ProX BoltX line built for stage lighting, concerts, obstacle course structures, and similar work. Three feet suits booth headers, small DJ facades, short uprights on totems, and filling out a span where the next size up overshoots the room.

BoltX uses a heavy-duty aluminum end plate welded on both sides, plus circular rings at each corner that take the abuse box truss actually sees: dropped ends, dragging across concrete, tight truck packs. Those rings protect the main chord ends, which is where expensive tube repairs usually start.

Each section includes one set of four 5/8" - 11 x 2.5" NC attachment bolts with nuts, flat washers, and lock washers, so you can connect a span the day it arrives. The industry-standard 6 3/4" x 6 3/4" bolt center pattern with 5/8" holes ties into most other 12" box truss using the same 6.75" bolt center. Main chords are 2" outer diameter with a 3mm wall and diagonals are 1" with a 3mm wall, welded from 6082-T6 alloy by GSI SLV-certified welders to TUV standards. Finish is black coated aluminum. Every segment is load tested and inspected during manufacturing and quality control.

Important: all bolts in a span must face the same direction, and uprights need bolts on top with nuts on the bottom. Tighten from the nut side with a ratchet, only a few turns past firm, and use washers on both sides of every connection. Inspect bolts regularly, replace bolt sets periodically, and check all connections and rigging before raising a build.
