Spiral Anchors Spiral Anchors can be used to fix lightweight objects onto finished external wall insulation systems, such as washing lines and outdoor lighting. These Spiral Anchors are made of plastic and are therefore ideal for ensuring a strong and secure hold, while also keeping thermal bridging at a minimum. Spiral Anchors can be easily screwed or drilled into the insulation system using an electric drill. We recommend fixing a maximum of 5kg per anchor to reduce any risk of hard-to-repair damage to the EWI system. Recommended Maximum Load: 5kg
