Stair tread bolts Set 1C – T = 35 mm – 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 1C in INOX A2 screws directly into hardwood. With an 18 mm gap between the tread and the timber structure, the embedment depth is T = 35 mm. For flush installation, it is T = 53 mm. This version has no sound insulation and is intended for single-family homes.
Choose the correct version
The wood species and grain direction determine the required embedment depth. Refer to the dedicated Set 1C table in the product gallery.
