Stair tread bolts Set 7C – simply rest the treads on the supports and screw them in place
Rest the treads on the supports and screw them in place – no additional tread machining required. Version C is the most economical LamiFIX system for fixing stair treads at the side. The tread connector requires neither a groove nor a mounting hole in the tread. This saves machining time, installation time and costs.
Application and design
Set 7C in INOX A2 is used to fix stair treads in concrete. The stair tread bolt is driven in with a sound-insulating plug. There is an 18 mm gap between the tread and the wall; no wall stringer is required.
Installation and supplied components
Installation requires a wall hole of Ø25 mm and 85 mm depth. The Set includes the stair anchor, sound-insulating plug, wall rosette and TX tread fixing screw.

This sound-insulated version is intended for multi-family buildings.
Installation with sound insulation
The wall hole is Ø25 mm in diameter and 85 mm deep. The sound-insulating plug is slightly oversized. Moisten it with a little soapy water before driving it in with a rubber mallet. Then place the tread on the support and screw it in place.
Accurate holes with drill bushes
The holes must be drilled at the correct angle and position. For stairs without stringers, we lend suitable drill bushes free of charge for a maximum of three months. The drilling guide is shown in the LamiFIX catalogue on page 26 .
Suitable drill bits and installation tools
Available separately:
Compatible with tread suspension systems
Version C can also be combined with LamiFIX tread suspension systems. Depending on the stair design, choose between the Ø10 mm tread suspension system and the Ø16 mm tread suspension system . The treads are suspended from the handrail or ceiling; the rods are made to measure.
