When you're setting structural steelwork into concrete, precision and stability are non-negotiable. That’s where waxed cardboard cones come in.

Designed to suit M16–M24 bolts at 300mm length, these waxed cardboard cones create a clean void around the bolt, allowing for easy adjustment and alignment once the concrete has cured.

The waxed finish prevents moisture absorption, maintaining the cone’s shape and integrity during the pour. That means no swelling, no distortion—just a reliable cavity that keeps your bolts exactly where you need them. Whether you're installing base plates, columns, or heavy-duty fixings, these cones streamline the process and reduce the risk of misalignment.

Each cone is engineered for compatibility with standard holding down bolts, making them ideal for use in commercial construction, civil engineering, and industrial settings. And because they’re made from biodegradable cardboard, they’re a smart choice for environmentally conscious builds.
