Seismic Bracing for Pipework, Ductwork and Cable Trays

Wire-rope bracing that holds suspended pipework, ductwork and cable trays in an earthquake. Installed with a little slack, it engages only after 6 mm (1/4″) of movement, so it works with isolated services as well as rigidly hung ones.

    Rod Stiffener

    Clamps the hanger rod to an angle so it does not buckle when the brace’s pull puts the rod into compression.

    Fits ACH-L channels and 25×25 to 40×40 mm angles · zinc plated

Datasheet ratings apply only to complete ASB-GRP kits, or to assemblies built entirely from Acrefine rope, grips and brackets. Mixing in components from other sources voids them.

The design behind the bracing

Which runs to brace, how far apart and to what load is a design question, answered before the hardware is chosen. We do that design as a service of its own.
