Product description
Fischer TBB – single fixing for wooden stair treads on concrete
Fischer TBB is a special fixing designed for installing wooden stair treads on concrete stair structures and other solid building materials. The nylon plug expands during installation, while its flexible geometry absorbs vibrations and helps reduce squeaking.
This offer is for 1 TBB fixing taken from the original fischer article 60583 pack containing 50 pieces.
When is it worth buying Fischer TBB individually?
The single-piece version is intended for customers who need one or several fixings for a repair, replacement or small installation and do not need the complete factory pack of 50 pieces.
The technical parameters of the individual fixing are the same as those of the elements contained in the original fischer 60583 pack.
Applications of the TBB fixing
TBB is designed for fixing wooden stair treads and wooden boards thicker than 30 mm to concrete and other solid building materials. Tightening the appropriate screw causes the nylon plug to expand inside the drilled hole.
Fischer states that optimum fixing strength can be achieved with the additional use of cold-setting wood adhesive. Plastic shims from the TBB system can be used to compensate for uneven substrates.
Key benefits
- possibility to purchase a single fixing instead of a full pack,
- designed for wooden stair treads on concrete stairs,
- suitable for concrete and other solid building materials,

How to prepare the installation holes?

The system is designed for wooden elements thicker than 30 mm. Before installation, make sure that the substrate is concrete or another solid building material.
