Product description
Fischer TBB 60583 – fixing for wooden stair treads on concrete 50 pieces
Fischer TBB is a special fixing system designed for installing wooden stair treads on concrete stair structures and other solid building materials. The flexible geometry of the nylon plug absorbs vibrations and helps reduce squeaking, improving the comfort of use of wooden stairs.
This offer includes one original factory box containing 50 Fischer TBB fixings.
What is Fischer TBB used for?
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 prepared 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 also be used to compensate for uneven substrates and help level the stair tread.
