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.

Top Features

• 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.

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.

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.

Applications

• Wooden step treads
