Hook Clamps

Standard 50mm Hook Clamps

Doughty's core 50mm hook clamp range covers the standard 48-51mm truss tube diameter at a wide spread of WLL ratings depending on duty level: Standard (40kg), Light Duty, Medium Duty (100kg), Heavy Duty (150kg), and the top-rated Hook Clamp w/M12 fixings at 750kg. Variants for specific jobs include the Extra Long, Straight End, Double Ended (150kg), and Double Ended & 180° Twist (40kg), the last available across five truss centre spacings from 150mm to 600mm.

Atom Hook Clamps: 25mm to 38mm

For smaller tube diameters, the 25mm, 32mm, 35mm and 38mm Hook Clamps all share a 100kg WLL rating.

Small and Large Tube Hook Clamps

Below the Atom range, the 18mm, 20mm (15kg WLL) and 30mm (15kg WLL) clamps suit smaller fixtures and lighter tube. At the larger end, the 60-75mm Hook Clamp and the Mammoth range, including the 60-63mm Slim Hook Clamp (300kg WLL), cover the larger 60mm+ tube diameter.

Lightweight and Slimline Variants

Where reducing weight matters more than maximum capacity, the Lightweight Hook Clamp (500kg WLL), Slimline Hook Clamp (750kg WLL) and Slim & Lightweight Hook Clamp (300kg WLL) each trade a different balance of weight versus capacity. The Compact Hook Clamp with M12 Fixings (500kg WLL) reduces the offset from tube to fixture in a smaller footprint.

Eye (Hanging) Clamps

An eye clamp combines a hook clamp body with a fixed eye rather than an open hook, giving a defined attachment point for a safety bond or additional rigging. Options span the 25mm, 32mm and 38mm Atom Hanging Clamps (100kg WLL each), up to the 48mm range: standard, Slimline (340kg), Slimline Lightweight (300kg) and the top-rated 48mm Hanging Clamp with SWL 750kg. A 60mm Slimline Hanging Clamp (300kg WLL) covers the Mammoth tube diameter.

TV and Broadcast Hook Clamps

The TV Clamp w/29mm Receiver (250kg WLL) and Alu. Hook Clamp 50mm w/29mm TV Spigot (150kg WLL) suit broadcast fixtures needing a 29mm receiver or spigot connection rather than a standard hook attachment. The TV Quick Clamp (100kg WLL) prioritises fast fitting on studio sets with frequent set changes.

All Weather Range

For outdoor and touring rigs exposed to the elements, the All Weather range includes the All Weather Trigger Hook Clamp, All Weather Slimline Hook Clamp, All Weather Slimline Lightweight Hook Clamp and All Weather Slimline Quick Trigger Hook Clamp, built for exterior installations where corrosion resistance matters.

Marquee, Scissor and Claw Clamps

The Marquee Clamp, available in Light (20kg), Medium (150kg) and Heavy-Duty (250kg) SWL, is designed for marquee and temporary structure fixings rather than truss. The Scissor Clamp (100kg or 250kg SWL) fits both girders and tubes, and the Claw Clamp, available across four plug sizes, provides an alternative attachment style to a standard hook.

TÜV-Approved Kits and Specialist Clamps

The Fifty Clamp - TÜV Approved (50kg WLL, 18 pieces) and Twenty Clamp - TÜV Approved are supplied as certified sets for installations needing documented compliance. The Clamp with Easy Grip Handle (750kg WLL) adds a handle for faster hand-tightening without tools, and the Hook Clamp w/16mm Baby Pin (40kg WLL) integrates a baby pin connection directly into the clamp body.

Warranty and Load Ratings

All hook clamps sold by MTN Shop EU are genuine Doughty stock, sourced through official distribution, so full manufacturer warranty applies as it would from the brand directly. WLL varies enormously across this range, from 15kg on small-tube clamps to 750kg on the heaviest 50mm variants, so always confirm the exact model's rating rather than assuming based on tube size alone.

Choosing the Right Hook Clamp

Match tube diameter first (18-38mm Atom range, standard 48-51mm, or 60mm+ Mammoth), then choose duty level based on the fixture weight, always leaving margin below the rated WLL. For fixtures that need a fixed attachment point for a safety bond, choose an eye (hanging) clamp rather than an open hook. For outdoor installations, the All Weather range is built specifically for exterior corrosion resistance.
