The + product

  • Floor box modular to compose : matchs with your needs (type of installation, number of modules, finishes), gives time for reflexion, protects the product during the progression of the work site (the installation follows the steps of the site).
  • Upgradability : without retouching the floor, a standard floor box initially installed can be replaced by a flush one and vice versa. Especially useful for tertiary rental buildings.
