No creaking due to elastic shaft geometry. This absorbs vibrations.
Also suitable for slimline steel profiles due to a short expansion zone.
Made of high-quality nylon.
The advantages / Product description
For attaching wooden step treads in steel sub-constructions.
Advantages
The elastic shaft geometry allows for the absorption of vibrations, prevents creaking, and thus increases comfort.
The TB only requires a very small cavity due to the short expansion element. Thus it is suitable even for narrow steel profiles.
The fischer stair-tread fixing TB is a fixing solution for mounting wooden stair treads on steel staircase stringers. The special fixing consists of a fixing sleeve made of high-quality nylon and a suitable screw. When driving in the screw, the fastener expands in the steel profile. Afterwards, the fastener is bonded in the wood step using cold wood glue.

Assembly instruction
Functioning
The plastic expansion plugs are suitable for anchoring wooden step treads and wooden boards >30 mm to steel profiles.
The ideal retention forces are only achieved when using cold wood glue for the fixing in wooden step treads.
