Stair tread bolt Set 7B – acoustically isolated fixing in concrete
LamiFIX stair tread bolt Set 7B fixes treads to the side of concrete walls. Version B is designed for treads with a drilled recess. The connector is inserted into the hole in the tread. The INOX Decor cover cap conceals the screw fixing.
Installation in concrete
The stair anchor is inserted into the concrete wall with the acoustic plug. The wall rosette covers the junction with the wall. The plaster must not exceed 15 mm in thickness. According to catalogue page 22, the wall hole must be 85 mm deep and 25 mm in diameter.
Acoustic isolation
Installation with acoustic isolation is recommended for apartment buildings. For single-family homes, it can generally be omitted.
Installation and drilling template
Wall holes must be drilled on site accurately in angle and position. Installation uses an acoustic plug.
For stairs without stringers, we lend matching drill bushes free of charge for up to three months. Installation using a template and drill bushes is shown in the LamiFIX catalogue on page 26 . For concrete, use the matching bushes for masonry drill bits.

Installation tip
Drill the wall hole to Ø25 mm. The acoustic plug is slightly oversized and is driven into the hole with a rubber mallet. Moisten it with a little soapy water before driving it in. This reduces friction and makes installation easier.
