At INDEX, we continue to improve our fastening solutions to make the daily work of installers and distributors simpler, safer, and more efficient. That’s why, from now on, the TN4S-A plug, the wide-collar version of the TN4S range, will be available in blue.
Why this change?
The new blue color of the TN4S-A allows for immediate identification on site, in warehouses, and at points of sale. This change offers a key advantage for professionals working with various plug references who need to quickly distinguish the wide-collar version.
This color change will be available in both sales formats: cardboard box and plastic jar.



A plug for all types of materials
Thanks to its four-way expansion, TN4S nylon plugs are suitable for solid materials —such as concrete, stone, or solid brick— as well as hollow materials, including perforated brick or plasterboard.
The new blue TN4S-A retains all the features that have made it a benchmark in fastening. Its extra-wide collar acts as a stop, ensuring flush installation and preventing unwanted movement.
Within the range, the new blue TN4S-A stands out for its extra-wide collar, which acts as a stop and ensures controlled, flush installation. Although it is a multi-material plug, it is especially designed for applications in hollow brick and plasterboard, where its design allows for quick, effective, and hassle-free installation.
The blue TN4S-A is now in stock and ready to be added to your catalog and shelf, clearly distinguished from the rest of the TN4S references, which remain in grey.
