ProX HOF MLT THREE 8-Foot Pre-Rig Truss and Folding Dolly Kit

We are proud to present the ProX XTH-MLT3KIT8FTFD HOF MLT THREE 8-Foot Pre-Rig Truss and Folding Dolly Kit, the complete, ready-to-deploy solution for production professionals who cannot afford to waste time on load-in. This kit pairs the HOF MLT THREE 8-foot pre-rig truss with its purpose-built folding dolly into a single bundle, giving touring companies, professional rental operations, and large-scale event contractors everything they need to get from truck to stage faster and more efficiently than ever. If you run productions on a tight schedule and a demanding calendar, this is the combination that makes it all work.

What Is Included This kit includes two purpose-matched components, sold together as a complete system: the HOF MLT THREE 8-foot pre-rig truss section with steel rotatable fork connectors (male and female), and the matching HOF MLT THREE folding dolly designed specifically for this truss series. These two products are engineered to work as a system, and buying them together means your truss and transport solution arrive matched and ready to go.

HOF MLT THREE 8-Foot Pre-Rig Truss The HOF MLT THREE is the pre-rig truss that major touring production companies and professional rental houses across Europe have relied on for years. It is now available in North America exclusively through ProX Live Performance Gear. The truss is built from aerospace-grade Aluminium EN AW 6082 T6, with a 48.3 x 4.5 mm main tube and 30 x 3 mm bracing, and finished with HOF's proprietary Heavy Duty (HD) powder coating in RAL 9005 gloss black. This finish bonds harder and resists chipping, scratching, and abrasion at a significantly higher level than standard powder coat, which matters when your truss is going in and out of trucks every week.

Open-Bottom Design for Unrestricted Rigging The MLT THREE features an open-bottom design with no closed head frame. This gives your crew full, unobstructed access to mount moving lights, LED fixtures, and video modules directly inside the truss. There is no fighting the structure. That means faster load-ins, cleaner rigs, and less fatigue across a long run.

LED Video Wall Applications The ProX XTH-MLT3KIT8FTFD is purpose-built for LED video panel rental work. The open-bottom clearance allows you to mount complete LED video modules, including hanging frames, directly inside the truss. Leave your panels fully loaded, roll the entire assembly onto the dolly, transport it to the next venue, and fly the rig right back up without disassembly. For rental companies running LED video walls from show to show, this workflow alone saves hours of labor per event and significantly reduces the risk of panel damage during transport.

Steel Rotatable Fork Connectors, Male and Female The truss ships with both male and female rotatable fork connectors made from hardened steel. The forks extend up to 60 mm and rotate to form vertical or horizontal curves at varying radii, giving your team the flexibility to build straight runs, curved rigs, or full circular overhead configurations from the same hardware. Connectors are individually field-replaceable, so a damaged fork on a rough load-in does not sideline the truss.

Unique Fork-Locking System™   "Lock It and Forget It" Mechanism -  One of the standout features of the ProX XTH-MLT3KIT8FTFD is the Unique Fork-Locking System™, and once you use it, you will wonder how you worked without it. The rotatable forks let you set your truss at any angle you need, making it simple to build 3D shapes, custom tower configurations, or even perfect truss circles using your standard inventory. Adjusting angles for curves and full circular rigs is no longer a production headache. And here is the part that really matters on tour: once you have the right angle dialed in, you lock it in the warehouse and it stays exactly where you set it through transport and through the show. No shifting. No adjustment needed on site. Just show up and build.

Pre-Tension Your Rig. Defeat the Deflection  Anyone who has hung a heavy LED wall knows the problem. The truss sags, the panels shift, and suddenly you have gaps in your screen in front of a packed house. The Unique Fork-Locking System™ on the ProX XTH-MLT3KIT8FTFD solves this at the source. Before the truck even leaves the warehouse, you can set a pre-tension, also known as a camber, directly into the truss to compensate for the weight of your LED panels and the truss itself. Lock it in, load it out, and it arrives on site already set to counteract the deflection. The wall goes up straight, and it stays that way.

Cross-Brand Compatible with 48.3 mm Truss Systems The industry-standard 48.3 mm main tube diameter and the included male and female fork connectors allow the ProX XTH-MLT3KIT8FTFD to connect directly to truss systems from other leading professional manufacturers without adapters or custom hardware. If your shop already runs trussing from multiple brands, this truss integrates directly into your existing inventory.

Comprehensive Structural Documentation Full structural analysis documentation is available for download, covering standard line loads, vertical use, upside-down configurations, horizontal and vertical curved builds, and cantilever applications. This is the paperwork your rigging team needs when pulling permits for large venue installs and permitted events.

HOF MLT THREE Folding Dolly The dolly included in this kit is purpose-built for the ProX XTH-MLTPFDUS8FT HOF MLT THREE 8-foot pre-rig truss. It is not a generic cart. Every dimension and feature is engineered to fit and function within the MLT THREE system, so your truss moves, stores, and deploys exactly as intended. The dolly is built from Aluminium EN AW 6082 T6, the same high-strength alloy used in the truss itself.

Save on Repairs, Not on Quality Accidents happen on tour. If a connector on the ProX XTH-MLT3KIT8FTFD gets damaged, you do not have to write off the entire truss section. Simply unscrew the fork, swap in a replacement, and you are back in business. Fast turnaround, low cost, and no wasted inventory sitting on a shelf because of one broken component.

Foldable and Stackable Construction When the show is over, the dolly folds flat for compact storage and stacks with other units, up to 10 pieces without truss, so you load out fast without wasted truck space.

Telescopic Adjustable Legs The dolly features telescopic adjustable legs. Remove the upper locking pin and the legs extend to accommodate full video modules, including hanging frames, so your pre-rig truss can be transported fully loaded without disassembly. The pin locks everything securely in place for safe movement.

Open-Bottom Dolly Design The open-bottom structure of the dolly gives you direct access for mounting moving lights and video modules underneath the truss while it sits on the cart. You can work on your pre-rig while it is still on the dolly, saving time during build before the truss ever goes up.

Heavy-Duty Casters The dolly rides on heavy-duty casters built to handle the weight of a fully loaded 8-foot truss section and roll smoothly across venue floors, loading docks, and backstage surfaces under full load.

Rotable Steel Fork Connectors on the Dolly Steel rotable fork connectors on the dolly screw out up to 70 mm, allowing horizontal or vertical circle configurations in a range of diameters. These connectors are replaceable when worn.

Single-Person Operation Hinged adjustable legs allow a single crew member to connect the truss to the dolly without needing a second set of hands. That kind of practical design cuts setup and teardown time on the floor.

Cross-Compatible Across MLT THREE Series Trusses and dollies from both MLT THREE series can be combined without compatibility issues, and the extended accessory range for the complete MLT THREE line keeps your system scalable as your production needs grow.

Kit Weights Truss: approximately 107.8 lbs. Dolly: 60 lbs.
