Installation procedure:
1.Drill hole at proper diameter and depth. Diameter is determined by on-site testing.
2.Insert friction bolt into the hole. A driving tool is fitted into the rock drill’s chuck. Place friction bolt and plate onto the installation tool.
3.Using percussion and thrust, fully drive the friction bolt into the hole until the dome plate is tight against the rock surface.
