Doughty Safety Bonds — 5kg -100kg

Doughty Safety Bonds — Stage Lighting Safety Wire

Doughty safety bonds are professional safety wires made from black wire rope, designed to provide a secondary fixing for rigged lighting fixtures in theatres, studios, schools, and live event venues. Also known as safety cables or safety bond wire, they act as a backup in case the primary clamp or fixing fails — preventing lighting fixtures from falling and protecting people below. Available in six variants — including the popular Doughty 15kg safety bond — with a safe working load ranging from 5kg to 100kg, and in lengths from 500mm to 1000mm, there is a Doughty safety bond to suit every fixture from lightweight barn doors to large moving heads.

Each Doughty safety bond is manufactured in-house at Doughty's UK factory, marked with a WLL, serial number, and company details on a heat shrink sleeve for full traceability — and each batch comes with its own test certificate. British designed and manufactured by Doughty Engineering, these bonds are trusted by rigging professionals across theatre, broadcast, and live events.

Always select a bond with a safe working load equal to or greater than the weight of the fixture being secured. Check your local health and safety regulations and venue risk assessment requirements before rigging.
