EVT50C-TNTCNC

Product Description

The EVT50C-TNTCNC is an adjustable steel beam clamp engineered for production riggers, structural contractors, and event crews who need a rated attachment point on an I-beam, Keder tent track, or structural rail where standard round-tube clamps won't seat. The jaw adjusts from 40mm to 130mm to accommodate the flange width variation across steel and aluminum I-beams, Keder track profiles, and most industry-standard rails in the 50mm to 110mm operating range. Five pre-threaded holes — M10 (x2), M12 (x2), and M14 (x1) — give the installer multiple attachment positions for rigging hardware, fixture yokes, or a direct connection to the EVT50C-BEHNC extra heavy-duty truss clamp, creating a complete beam-to-fixture mounting solution without fabricating a custom bracket. The S-handle tightening mechanism locks the jaw to the beam flange without tools. Rated at 220 lb (100 kg) safe working load and TUV Rheinland Certified. Body constructed from Q235 carbon steel with a brushed finish.

Key Features

• 40mm to 130mm adjustable jaw: A single clamp accommodates the flange width variation across structural steel I-beams, aluminum I-beams, Keder tent track profiles, and standard rails in the 50mm to 110mm operating range — no size-specific clamp required for each beam type.
• Five pre-threaded holes — M10, M12, M14: Multiple attachment positions for rigging hardware, fixture yokes, and accessory brackets. Thread the EVT50C-BEHNC directly into the M12 hole for a complete I-beam to 2-inch truss clamp position in seconds.
• Direct EVT50C-BEHNC compatibility: The pre-threaded M12 hole accepts the EVT50C-BEHNC extra heavy-duty narrow truss clamp — beam to fixture in one stacked assembly, no custom fabrication required.
• S-handle tightening mechanism: Locks the jaw to the beam flange without tools — fast to set, secure under load, and quick to reposition when the hang point changes.
• 220 lb (100 kg) safe working load: TUV Rheinland Certified for professional rigging and production applications.
• Q235 carbon steel body: Structural steel construction rated for the clamping forces and dynamic loads common in production and industrial environments.
• Overall dimensions: 135.5mm W x 150mm H x 53.8mm D — compact profile for use in tight overhead clearances.
• 1-year limited warranty against manufacturing defects.

Who It's For

• Structural steel riggers and industrial facility contractors: Your production facility, warehouse, or industrial space has exposed steel I-beam infrastructure and you need to add lighting, cable management, or equipment mounts to existing structural steel without drilling or welding. The EVT50C-TNTCNC clamps directly to the I-beam flange within the 50mm to 110mm range, creating a rated load point with a pre-threaded hole for any M10, M12, or M14 fastener — the same sizes used across standard rigging hardware. Thread in the EVT50C-BEHNC and you have a full 2-inch truss clamp position on any I-beam in seconds, without touching the structural steel.
• Event lighting companies working in non-traditional venues: You're designing lighting for a loft space, warehouse, aircraft hangar, or industrial venue with structural steel I-beams overhead instead of purpose-built rigging points. Standard truss clamps are designed for round tube — they don't grip a flat I-beam flange. The EVT50C-TNTCNC fills that gap, giving you a rated attachment point on any accessible I-beam flange within the adjustment range. Thread the EVT50C-BEHNC into the M12 hole and you have a complete I-beam to fixture hanging solution without fabricating anything custom on site.
• Tent and structure rental companies: You install Keder frame tents and clear-span structures for weddings, corporate events, and outdoor festivals, and clients regularly ask to hang lighting, draping hardware, or AV equipment from the tent structure. The EVT50C-TNTCNC fits the Keder track beam profile and provides a rated, documented load path for suspended accessories — giving your crew a professional answer to a request you'd otherwise have to decline or improvise around.
• Touring production crews working in varied venues: Your tour advances into a different venue at every stop — some with purpose-built rigging points, others with exposed building steel, and some with temporary tent or canopy structures. A beam clamp in the truck that adjusts from 50mm to 110mm handles the majority of structural steel flange widths your crew will encounter across the routing without carrying a set of size-specific clamps for each venue configuration.

Compatibility — Read Before You Buy

• Adjustment range: The EVT50C-TNTCNC operates on flanges from 50mm to 110mm. Verify your I-beam or track flange width before ordering — the jaw will not close securely on flanges outside this range.
• Threaded hole sizing: Pre-threaded holes accept M10, M12, and M14 fasteners only. Confirm the thread specification of your rigging hardware before assembly.
• Load path: The 220 lb (100 kg) SWL applies to the clamp-to-beam connection. The total assembly load rating is limited by the lowest-rated component in the chain — verify the SWL of all attached hardware independently.
• Surface condition: The jaw must seat fully and evenly on a clean, undamaged beam flange. Do not use on corroded, deformed, or painted flanges where surface condition could affect grip.

Safety and Engineering

• Load rating: Do not exceed the rated safe working load of 220 lb (100 kg). Never use this clamp for loads beyond its rated capacity.
• Pre-use inspection: Inspect the jaw, S-handle, and all threaded holes before every use. Remove from service immediately if any component shows deformation, thread damage, or incomplete jaw closure.
• Secondary safety: The use of safety cables is mandatory for all overhead rigging applications.
• Tightening: The S-handle must be fully tightened against the beam flange before any load is applied. Verify jaw contact is even across the full flange width.
• Engineering review: The purchase of this product does not authorize or approve a specific installation or use. A licensed professional engineer shall review all structures, rigging plots, or other clamp uses.
