THE CONCEPT
1
▶T4BLOK is a woodworking tool designed for assembling wooden slats
of the building: cladding, terrace, flooring, paneling…
▶ It allows you to straighten wooden blades that have been deformed by machining,
transport or storage.
2
▶The T4BLOK attaches to the frame and allows you to compress several rows of wooden boards simultaneously.
▶ For decking installation, use intermediate spacers of equal thickness.
▶ For optimal compression, place an aluminum straightedge between the tool and the boards to evenly distribute the force.
3
▶ T4BLOK can be used on its own. On long installation runs, using a tool every 150 to 200 cm is recommended.
▶ The claws allow the tool to lock securely onto the support.
▶ T4BLOK is fully reversible for right- or left-handed operation.
Straighten & align up to
10 boards in a single push!

Since September 2022, the INIZIA incubator, specialized
in supporting innovative projects, participates
in the various phases of development of the T4BLOK tool by providing advice and expertise.

In December 2023, the BPI will award a grant to continue the completion of the prototype, the production of a pre-series and the extension of the patent internationally.

Since early 2024, ADEC—a key player in the economic development of innovative businesses in Corsica—has been involved in the R&D, prototyping, and pre-production phases of our tool, granting us an essential subsidy.
Throughout all the R&D phases, from the finalization of the prototype to negotiations with numerous French manufacturers, Mr. Dominique CAYRON,
ELPMI-Consulting was able to provide its expertise based on very solid experience in product design and industrial processes.
REVIEWS
David Duquenoy
Delta Bois
A powerful and clever tool that straightens up to 7 decking boards at once. It can also be used for siding. While the price might be a bit steep, for a professional contractor, it is an investment that quickly pays for itself. I highly recommend the product.
A great product! Ideally, you should have two or even three of them to work on longer runs. A real time-saver, especially for aligning and keeping boards parallel.

Great value for money, saves time and effort—very happy with my purchase.
