Portable/reusable anchorage connectors designed for use in concrete applications or with a Friction Bolt (specific models). A safe anchor point is established when the Miller Grip anchor is inserted into a properly-sized, cured concrete hole. The reusable Miller Grip anchor can be removed and simply re-installed in a new location. Multi-use Grips can be used for anchoring scaffolding, material handling and removal of concrete debris after demolition.
