The perfect anchor for quick, reliable fixings in uncracked concrete and for suspended ceilings
The stud anchor B A4 is particularly suitable for time-saving in-place installation in uncracked concrete, and for suspended ceilings. The reduced embedment depth expands the range of applications, e.g. for reinforcement chamfers and for low loads.
Application area:
For securing
supports, beams, metal structures, brackets, cable conduits, mounting rails, suspended ceilings etc.
to
uncracked normal weight concrete with a strength class of ≥ C20/25 and ≤ C50/60, also for use outdoors or in wet rooms if conditions are not particularly aggressive.
Advantages:
- High permissible loads, low spacing and edge distance
- Quick and easy in-place installation
- Immediate load-bearing capacity - no waiting
- The long thread allows anchors to be used for different clamping widths. Furthermore, it allows stand-off installations and other applications requiring larger clamping lengths or reduced effective anchorage depths.
- Reduced effective anchorage depths possible, e.g. for reinforcement chamfers or for low loads
- Three effective anchorage depths for flexible use
