Newton MultiPlugs have a rubber sealing grommet supplied with the plug.
In very poor substrate, a pin (supplied in bags of 100 at extra cost) is inserted into the plug that expands its outer circumference by nearly 2mm to tighten the plug into the substrate. The MultiPlug is pre-drilled to accept a size 10 (5mm) self-tapping screw for the fixing of battens or other dry-lining systems.
