Is the EVT50C-ALC compatible with Global Truss MINI 360 systems?

Yes. The EVT50C-ALC shares the same 48–51mm tube compatibility and 100 kg load rating as the MINI 360, making it a direct drop-in alternative for F31, F32, F33, F34, and DT44P truss systems. The EVT50C-ALC is not manufactured by or affiliated with Global Truss.

What hardware comes with the EVT50C-ALC?

Each clamp includes an M10 x 30mm S45C carbon steel bolt and spring lock washer. S45C is a medium-carbon structural steel (equivalent to AISI 1045) commonly used for high-strength fasteners and machine components.

What is the safe working load of the EVT50C-ALC?

The EVT50C-ALC is rated at 100 kg safe working load (SWL) and 30 kg maximum shear load, with a tensile strength of 4.9 kN. It is TUV Rheinland certified. Always follow proper rigging practices and do not exceed rated load capacity.

Tube and Truss Compatibility

F33, F34, EVT290S, and Other 48–51 mm Truss Systems.

The EVT50C-ALC is designed for 48–51 mm outside-diameter tubing. Compatibility depends on the actual tube diameter, wall condition, clamp seating, attachment hardware, and the engineering requirements of the complete installation.

EVT290S Compatibility

Fits compatible EVT290S truss using 50 mm main chords.

F34 Compatibility

Compatible with matching F34 square truss using 48–51 mm main-chord tubing.

F33 Compatibility

Compatible with matching F33 triangular truss using 48–51 mm main-chord tubing.

Other Truss Systems

Verify the actual tube diameter and full system data before use. Exact fit with other brands or systems is not guaranteed.

Installation Sequence

Install the Clamp with Full Tube Contact and Verified Hardware.

01 — Verify Tube Diameter

Confirm the supporting tube measures within the documented 48–51 mm range.

02 — Inspect the Clamp

Check the aluminum body, hinge, bolt, threads, and spring lock washer before use.

03 — Seat the Clamp

Position the clamp so the body wraps evenly around the tube without obstruction.

04 — Attach the Fixture

Use compatible attachment hardware and follow the fixture manufacturer's installation instructions.

05 — Tighten Correctly

Secure the connection without deforming the truss chord or damaging the clamp threads.

06 — Add Secondary Safety

Use an independently rated safety cable or secondary retention method whenever required.

Inspection and Maintenance

Inspect Before Every Use. Remove Damaged Hardware from Service.

Clamp Body

Check for cracks, deformation, deep gouges, corrosion, or visible impact damage.

Bolt and Threads

Inspect the M10 bolt and mating threads for stretching, galling, stripping, or contamination.

Lock Washer

Confirm the spring lock washer is present, undamaged, and correctly seated.

Tube Contact Surfaces

Keep the clamping surfaces clean and free from debris that could prevent full seating.

Service Records

Follow the inspection and recordkeeping procedures required by the venue, employer, or authority having jurisdiction.

Safety and Load Limits

Treat the Clamp Rating as One Part of the Complete Rigging System.

Do not exceed the 100 kg / 220 lb safe working load or the 30 kg / 66 lb maximum shear load.

The supporting truss, fixture, attachment bolt, safety cable, and all connected hardware must also be properly rated.

Use the clamp only on tubing within the documented 48–51 mm outside-diameter range.

Do not use a clamp that is cracked, bent, heavily worn, corroded, or has damaged threads.

Do not modify, drill, weld, grind, or heat the clamp body.

Use independent secondary retention for overhead fixtures whenever required by code, venue policy, or manufacturer instructions.

Installation and inspection should be completed by qualified personnel familiar with entertainment rigging practices.
