To fix wooden step treads in concrete and steel sub-structures.

Stair-tread fixing TB / TBB

The fischer stair-tread fixing TB is a fixing solution for installation of wooden stair-treads on steel stringers. Wooden step treads are fixed directly into concrete and solid building materials with the fischer stair-tread fixing TBB. The stair-tread fixing for steel sub-structures only requires a very small cavity due to the short expansion element. Thus it is suitable even for narrow steel profiles. The special fixing TB comprises a plug sleeve made from high-quality nylon and a corresponding screw. Screwing in the screw causes the fixer to expand in the steel profile. The stair-tread fixing TBB fixings in concrete and solid building materials comprises a plastic sleeve with a directly preshaped expansion plug shank.
