  Wedge Anchor for Cracked and Non-cracked Concrete
  Wedge Anchor BZ plus A4
   
   
 
   
Description
The Wedge Anchor BZ plus A4 (ETA, Option1) combines high approved loads with small anchor spacings and edge distances.
Time saving through fastening installations - no special drilling and setting tools are required. Tightening the hexagon nut expands the sleeve which produces permanent grip in cracked and non-cracked concrete. The BZ plus A4 is shock approved.


Applications
Medium to heavy duty anchorings in cracked and non-cracked concrete: steel beams, channels, facade substructures, chairs in sports arenas, wood structures.
