Fischer tassello di fissaggio per gradini TB per acciaio (confezione da 50 pezzi)

The plastic expansion plugs are suitable for anchoring wooden step treads and wooden boards >30 mm to steel profi les (TB) or in solid building materials (TBB). The elastic shaft geometry allows for the absorption of vibrations, prevents creaking, and thus increases comfort. The stair-tread fixing for steel substructures (TB) only requires a very small cavity due to the short expansion element. Thus it is suitable even for narrow steel profiles.
