Installation aid for centre-marking the stair-tread holes.
Advantages
The elastic shaft geometry allows for the absorption of vibrations, prevents creaking, and thus increases comfort.
The stair-tread fixing for steel sub-structures (TB) only requires a very small cavity due to the short expansion element. Thus it is suitable even for narrow steel profiles.
Special tool for centre-marking the wood stair-tread holes in connection with the fischer stair-tread fixing TB or TBB.

Functionality
The plastic expansion plugs are suitable for anchoring wooden step treads and wooden boards >30 mm to steel profiles (TB) or in solid building materials (TBB).
The ideal retention forces are only achieved when using cold wood glue for the fixing in wooden step treads.
The plastic washers included with the TBB allow you to level out any unevenness in the substrate.
