RAWLPLUG UNO Universal Plugs are the ideal solution for a variety of applications, especially when dealing with unknown substrates and exploited holes. Their short length ensures successful use in thin walls, while their unique geometry guarantees maximum expansion and grip. 100% assurance of proper anchoring is provided by the unique split design of the plug in its top part, and anti-rotation features prevent it from spinning in the hole. Furthermore, the lip prevents the plug from slipping into over-sized holes.
