The fischer Hose anchor TA M NL is a sleeve anchor with female thread suitable for temporary fixing in hollow-core concrete slab floors. The optimized anchor geometry minimizes the energy required for installation. During assembly, the cone is pulled into the expansion sleeve, which then spreads into the wall of the channel. The triple spreading sleeve guarantees the even distribution of the load. After disassembly, no protruding parts remain in the drillhole, thus preventing the risk of accidents.
