Doughty Trigger TV Clamp The Trigger TV Clamp is supplied fitted with a 29mm diameter receiver, designed predominantly for use in the TV/Film industry. This Doughty Clamp is designed to allow one person to hang heavy luminaires and scanners. The weight of the object being hung becomes its own safety factor by automatically closing the trigger and the bottom half of the clamp. This unique feature allows the luminaires to be easily positioned and securely ‘locked off’ with the large Easy-Grip handle fitted. Manufactured from high tensile aluminium extrusion, it is lightweight but extremely strong with a safe working load of 200kg. For any inquiries, please contact us via chat.
