Features & Applications

The ETA Hollow Concrete Anchors are a high-performance anchor for suspending mechanical services and electrical containment from hollow concrete ceiling slabs. The design of this anchor is such that it gives optimum performance in both solid and hollow materials allowing the installer flexibility in choosing the anchor locations.
TOOLBOX TALK - Torque Wrenches - BS 8539 stipulates that anchors should be tightened to the manufacturer's recommended torque settings. This will ensure that anchors are consistently set to achieve the maximum load and the anchor material is not over-stressed.
