Adjustable Square Tube Light Clamp for Trade Show Booth & Exhibition Lighting

Precision Grip for Square Profiles — No Slipping, No Guesswork

When your booth uses square tubing, standard round-jaw clamps never sit quite right. This compact, screw-adjustable G-clamp style light clamp is engineered specifically for square and rectangular profiles, giving you a flush, rock-solid hold that round-jaw C-clamps simply can't match.

Smaller and lighter than our universal C-clamp, it's the go-to universal booth light clamp for tight booth builds where every gram and every millimeter counts.

Why This Clamp Is Different

• Spiral screw adjustment — fine-tune clamping pressure precisely; works as a heavy duty C-clamp and adjustable C-clamp for lights on square profiles
• Optimized for square & rectangular profiles — flat jaw face grips square tubes flush; ideal as a square tube light clamp and crossbar lighting clamp
• Clamping range: 20–50mm (¾" to 2") — fits standard square booth frames, Octanorm panels, and display structures
• Aluminum truss clamp capability — also works as a truss mount clamp for exhibition lights and stage light clamp on square truss sections
• Trade show booth wall clamp — mounts securely on Octanorm booth wall panels; functions as an Octanorm booth wall clamp and exhibition panel light clamp
• Light box mounting clamp — doubles as a trade show display light bracket and display panel light clip for fabric lightbox frames
• Compact & lightweight — smaller footprint than round-jaw clamps, ideal for dense multi-light setups
• Aircraft-grade aluminum — corrosion-resistant, built for repeated show use
• Compatible with all BOOTH LIGHTS arm lights and spotlights
